Bits 0-15: NDT[15:0]: Number of data to transfer Number of data to be transferred (0 up to 65535). This register can only be written when the channel is disabled. Once the channel is enabled, this register is read-only, indicating the remaining bytes to be transmitted. This register decrements after each DMA transfer. Once the transfer is completed, this register can either stay at zero or be reloaded automatically by the value previously programmed if the channel is configured in auto-reload mode. If this register is zero, no transaction can be served whether the channel is enabled or not..

LOCK key write sequence: WR LCKR[16] = '1' + LCKR[15:0] WR LCKR[16] = '0' + LCKR[15:0] WR LCKR[16] = '1' + LCKR[15:0] RD LCKR RD LCKR[16] = '1' (this read operation is optional but it confirms that the lock is active) Note: During the LOCK key write sequence, the value of LCK[15:0] must not change. Note: Any error in the lock sequence aborts the lock. Note: After the first lock sequence on any bit of the port, any read access on the LCKK bit returns '1' until the next MCU reset or peripheral reset..

Allowed values:
0: NotActive: Port configuration lock key not active
1: Active: Port configuration lock key active

LOCK key write sequence: WR LCKR[16] = '1' + LCKR[15:0] WR LCKR[16] = '0' + LCKR[15:0] WR LCKR[16] = '1' + LCKR[15:0] RD LCKR RD LCKR[16] = '1' (this read operation is optional but it confirms that the lock is active) Note: During the LOCK key write sequence, the value of LCK[15:0] must not change. Note: Any error in the lock sequence aborts the lock. Note: After the first lock sequence on any bit of the port, any read access on the LCKK bit returns '1' until the next MCU reset or peripheral reset..

Allowed values:
0: NotActive: Port configuration lock key not active
1: Active: Port configuration lock key active

It is cleared by a write to the USARTx_TDR register. The TXE flag can also be set by writing 1 to the TXFRQ in the USART_RQR register, in order to discard the data (only in Smartcard T=0 mode, in case of transmission failure). When FIFO mode is enabled, TXFNF is set by hardware when TXFIFO is not full, and so data can be written in the USART_TDR. Every write in the USART_TDR places the data in the TXFIFO. This flag remains set until the TXFIFO is full. When the TXFIFO is full, this flag is cleared indicating that data can not be written into the USART_TDR. Note: The TXFNF is kept reset during the flush request until TXFIFO is empty . After sending the flush request (by setting TXFRQ bit), the flag TXFNF should be checked prior to writing in TXFIFO. (TXFNF and TXFE will be set at the same time).

SUBFS

Bits 0-14: Subtract a fraction of a second These bits are write only and is always read as zero. Writing to this bit has no effect when a shift operation is pending (when SHPF=1, in RTC_ISR). The value which is written to SUBFS is added to the synchronous prescalers counter. Since this counter counts down, this operation effectively subtracts from (delays) the clock by: Delay (seconds) = SUBFS / ( PREDIV_S + 1 ) A fraction of a second can effectively be added to the clock (advancing the clock) when the ADD1S function is used in conjunction with SUBFS, effectively advancing the clock by : Advance (seconds) = ( 1 - ( SUBFS / ( PREDIV_S + 1 ) ) ) ..

ADD1S

Bit 31: Add one second 0: No effect 1: Add one second to the clock/calendar This bit is write only and is always read as zero. Writing to this bit has no effect when a shift operation is pending (when SHPF=1, in RTC_ISR).

Bit 15: Increase frequency of RTC by 488.5 ppm 0: No RTCCLK pulses are added. 1: One RTCCLK pulse is effectively inserted every 211 pulses (frequency incresed by 488.5 ppm). This feature is intended to be used in conjunction with CALM, which lowers the frequency of the calendar with a fine resolution. if the input frequency is 32768 Hz, the number of RTCCLK pulses added during a 32-second window is calculated as follows: (512 * CALP) - CALM..

ASTREN

Bit 12: Asynchronous start enable. - 0: The Asynchronous start is disabled. When the I2S is enabled in slave mode, the I2S slave starts the transfer when the I2S clock is received and an appropriate transition (depending on the protocol selected) is detected on the WS signal. - 1: The Asynchronous start is enabled. When the I2S is enabled in slave mode, the I2S slave starts immediately the transfer when the I2S clock is received from the master without checking the expected transition of WS signal. Note: The appropriate transition is a falling edge on WS signal when I2S Philips Standard is used, or a rising edge for other standards..

SMS

Bits 0-2: SMS: Slave mode selection When external signals are selected the active edge of the trigger signal (TRGI) is linked to the polarity selected on the external input (see Input Control register and Control Register description. 0000: Slave mode disabled - if CEN = '1' then the prescaler is clocked directly by the internal clock. 0001: Encoder mode 1 - Counter counts up/down on TI2FP2 edge depending on TI1FP1 level. 0010: Encoder mode 2 - Counter counts up/down on TI1FP1 edge depending on TI2FP2 level. 0011: Encoder mode 3 - Counter counts up/down on both TI1FP1 and TI2FP2 edges depending on the level of the other input. 0100: Reset Mode - Rising edge of the selected trigger input (TRGI) reinitializes the counter and generates an update of the registers. 0101: Gated Mode - The counter clock is enabled when the trigger input (TRGI) is high. The counter stops (but is not reset) as soon as the trigger becomes low. Both start and stop of the counter are controlled. 0110: Trigger Mode - The counter starts at a rising edge of the trigger TRGI (but it is not reset). Only the start of the counter is controlled. 0111: External Clock Mode 1 - Rising edges of the selected trigger (TRGI) clock the counter. 1000: Combined reset + trigger mode - Rising edge of the selected trigger input (TRGI) reinitializes the counter, generates an update of the registers and starts the counter. Codes above 1000: Reserved. Note: The gated mode must not be used if TI1F_ED is selected as the trigger input (TS='100'). Indeed, TI1F_ED outputs 1 pulse for each transition on TI1F, whereas the gated mode checks the level of the trigger signal..

OCCS

Bit 3: OCCS: OCREF clear selection This bit is used to select the OCREF clear source. 0: OCREF_CLR_INT is connected to the OCREF_CLR input (stuck at 0 so no effect) 1: OCREF_CLR_INT is connected to ETRF.

ECE

Bit 14: ECE: External clock enable This bit enables External clock mode 2. 0: External clock mode 2 disabled 1: External clock mode 2 enabled. The counter is clocked by any active edge on the ETRF signal. Note: 1: Setting the ECE bit has the same effect as selecting external clock mode 1 with TRGI connected to ETRF (SMS=111 and TS=111). Note: 2: It is possible to simultaneously use external clock mode 2 with the following slave modes: reset mode, gated mode and trigger mode. Nevertheless, TRGI must not be connected to ETRF in this case (TS bits must not be 111). Note: 3: If external clock mode 1 and external clock mode 2 are enabled at the same time, the external clock input is ETRF..

Allowed values:
0: Disabled: External clock mode 2 disabled
1: Enabled: External clock mode 2 enabled. The counter is clocked by any active edge on the ETRF signal.

ETP

Bit 15: ETP: External trigger polarity This bit selects whether ETR or ETR is used for trigger operations 0: ETR is non-inverted, active at high level or rising edge. 1: ETR is inverted, active at low level or falling edge..

Each time the REP_CNT related downcounter reaches zero, an update event is generated and it restarts counting from REP value. As REP_CNT is reloaded with REP value only at the repetition update event U_RC, any write to the TIMx_RCR register is not taken in account until the next repetition update event. It means in PWM mode (REP+1) corresponds to the number of PWM periods in edge-aligned mode..

UE

Bit 0: USART enable When this bit is cleared, the USART prescalers and outputs are stopped immediately, and all current operations are discarded. The USART configuration is kept, but all the USART_ISR status flags are reset. This bit is set and cleared by software. Note: To enter low-power mode without generating errors on the line, the TE bit must be previously reset and the software must wait for the TC bit in the USART_ISR to be set before resetting the UE bit. Note: The DMA requests are also reset when UE = 0 so the DMA channel must be disabled before resetting the UE bit. Note: In Smartcard mode, (SCEN = 1), the CK is always available when CLKEN = 1, regardless of the UE bit value..

Allowed values:
0: Disabled: UART is disabled
1: Enabled: UART is enabled

UESM

Bit 1: USART enable in low-power mode When this bit is cleared, the USART cannot wake up the MCU from low-power mode. When this bit is set, the USART can wake up the MCU from low-power mode. This bit is set and cleared by software. Note: It is recommended to set the UESM bit just before entering low-power mode and clear it when exit from low-power mode. Note: If the USART does not support the wakeup from Stop feature, this bit is reserved and must be kept at reset value. Refer to Section53.4: USART implementation on page2587..

Note: During transmission, a low pulse on the TE bit ('0' followed by '1') sends a preamble (idle line) after the current word, except in Smartcard mode. In order to generate an idle character, the TE must not be immediately written to '1'. To ensure the required duration, the software can poll the TEACK bit in the USART_ISR register. Note: In Smartcard mode, when TE is set, there is a 1 bit-time delay before the transmission starts..

Allowed values:
1: Mute: Puts the USART in mute mode and sets the RWU flag

RXFRQ

Bit 3: Receive data flush request Writing 1 to this bit empties the entire receive FIFO i.e. clears the bit RXFNE. This enables to discard the received data without reading them, and avoid an overrun condition..

Allowed values:
1: Discard: clears the RXNE flag. This allows to discard the received data without reading it, and avoid an overrun condition

TXFRQ

Bit 4: Transmit data flush request When FIFO mode is disabled, writing '1' to this bit sets the TXE flag. This enables to discard the transmit data. This bit must be used only in Smartcard mode, when data have not been sent due to errors (NACK) and the FE flag is active in the USART_ISR register. If the USART does not support Smartcard mode, this bit is reserved and must be kept at reset value. When FIFO is enabled, TXFRQ bit is set to flush the whole FIFO. This sets the TXFE flag (Transmit FIFO empty, bit 23 in the USART_ISR register). Flushing the Transmit FIFO is supported in both UART and Smartcard modes. Note: In FIFO mode, the TXFNF flag is reset during the flush request until TxFIFO is empty in order to ensure that no data are written in the data register..

Allowed values:
0: NoError: No parity error
1: Error: Parity error

FE

Bit 1: Framing error This bit is set by hardware when a de-synchronization, excessive noise or a break character is detected.

When transmitting data in Smartcard mode, this bit is set when the maximum number of transmit attempts is reached without success (the card NACKs the data frame). An interrupt is generated if EIE=1 in the USART_CR3 register. Note: This error is associated with the character in the USART_RDR..

Allowed values:
0: NoError: No Framing error is detected
1: Error: Framing error or break character is detected

NE

Bit 2: Noise detection flag This bit is set by hardware when noise is detected on a received frame. It is cleared by software, writing 1 to the NECF bit in the USART_ICR register. Note: This bit does not generate an interrupt as it appears at the same time as the RXFNE bit which itself generates an interrupt. An interrupt is generated when the NE flag is set during multi buffer communication if the EIE bit is set. Note: When the line is noise-free, the NE flag can be disabled by programming the ONEBIT bit to 1 to increase the USART tolerance to deviations (Refer to Section53.5.8: Tolerance of the USART receiver to clock deviation on page2604). Note: This error is associated with the character in the USART_RDR..

Allowed values:
0: NoNoise: No noise is detected
1: Noise: Noise is detected

ORE

Bit 3: Overrun error This bit is set by hardware when the data currently being received in the shift register is ready to be transferred into the USART_RDR register while RXFF = 1. It is cleared by a software, writing 1 to the ORECF, in the USART_ICR register. An interrupt is generated if RXFNEIE=1 in the USART_CR1 register, or EIE = 1 in the USART_CR3 register. Note: When this bit is set, the USART_RDR register content is not lost but the shift register is overwritten. An interrupt is generated if the ORE flag is set during multi buffer communication if the EIE bit is set. Note: This bit is permanently forced to 0 (no overrun detection) when the bit OVRDIS is set in the USART_CR3 register..

Allowed values:
0: NoOverrun: No Overrun error
1: Overrun: Overrun error is detected

IDLE

Bit 4: Idle line detected This bit is set by hardware when an Idle Line is detected. An interrupt is generated if IDLEIE=1 in the USART_CR1 register. It is cleared by software, writing 1 to the IDLECF in the USART_ICR register. Note: The IDLE bit is not set again until the RXFNE bit has been set (i.e. a new idle line occurs). Note: If Mute mode is enabled (MME=1), IDLE is set if the USART is not mute (RWU=0), whatever the Mute mode selected by the WAKE bit. If RWU=1, IDLE is not set..

Allowed values:
0: NoIdle: No Idle Line is detected
1: Idle: Idle Line is detected

RXFNE

Bit 5: RXFIFO not empty RXFNE bit is set by hardware when the RXFIFO is not empty, meaning that data can be read from the USART_RDR register. Every read operation from the USART_RDR frees a location in the RXFIFO. RXFNE is cleared when the RXFIFO is empty. The RXFNE flag can also be cleared by writing 1 to the RXFRQ in the USART_RQR register. An interrupt is generated if RXFNEIE=1 in the USART_CR1 register..

Allowed values:
0: NoData: Data is not received
1: DataReady: Received data is ready to be read

TC

Bit 6: Transmission complete This bit indicates that the last data written in the USART_TDR has been transmitted out of the shift register. It is set by hardware when the transmission of a frame containing data is complete and when TXFE is set. An interrupt is generated if TCIE=1 in the USART_CR1 register. TC bit is is cleared by software, by writing 1 to the TCCF in the USART_ICR register or by a write to the USART_TDR register. Note: If TE bit is reset and no transmission is on going, the TC bit is immediately set..

Allowed values:
0: TxNotComplete: Transmission is not complete
1: TxComplete: Transmission is complete

TXFNF

Bit 7: TXFIFO not full TXFNF is set by hardware when TXFIFO is not full meaning that data can be written in the USART_TDR. Every write operation to the USART_TDR places the data in the TXFIFO. This flag remains set until the TXFIFO is full. When the TXFIFO is full, this flag is cleared indicating that data can not be written into the USART_TDR. An interrupt is generated if the TXFNFIE bit =1 in the USART_CR1 register. Note: The TXFNF is kept reset during the flush request until TXFIFO is empty.

0: NotCompleted: Transmission is not complete or transmission is complete unsuccessfully (i.e. a NACK is received from the card)
1: Completed: Transmission is complete successfully (before Guard time completion and there is no NACK from the smart card)

RXFT

Bit 26: RXFIFO threshold flag This bit is set by hardware when the threshold programmed in RXFTCFG in USART_CR3 register is reached. This means that there are (RXFTCFG - 1) data in the Receive FIFO and one data in the USART_RDR register. An interrupt is generated if the RXFTIE bit =1 (bit 27) in the USART_CR3 register. Note: When the RXFTCFG threshold is configured to '101', RXFT flag is set if 16 data are available i.e. 15 data in the RXFIFO and 1 data in the USART_RDR. Consequently, the 17th received data does not cause an overrun error. The overrun error occurs after receiving the 18th data..
