Allowed values:
0: Disabled: Circular buffer disabled
1: Enabled: Circular buffer enabled

PINC

Bit 6: peripheral increment mode Defines the increment mode for each DMA transfer to the identified peripheral. n memory-to-memory mode, this field identifies the memory destination if DIR=1 and the memory source if DIR=0. In peripheral-to-peripheral mode, this field identifies the peripheral destination if DIR=1 and the peripheral source if DIR=0. Note: this bit is set and cleared by software. It must not be written when the channel is enabled (EN = 1). It is read-only when the channel is enabled (EN=1)..

Allowed values:
0: Disabled: Increment mode disabled
1: Enabled: Increment mode enabled

MINC

Bit 7: memory increment mode Defines the increment mode for each DMA transfer to the identified memory. In memory-to-memory mode, this field identifies the memory source if DIR=1 and the memory destination if DIR=0. In peripheral-to-peripheral mode, this field identifies the peripheral source if DIR=1 and the peripheral destination if DIR=0. Note: this bit is set and cleared by software. It must not be written when the channel is enabled (EN = 1). It is read-only when the channel is enabled (EN=1)..

Allowed values:
0: Disabled: Increment mode disabled
1: Enabled: Increment mode enabled

PSIZE

Bits 8-9: peripheral size Defines the data size of each DMA transfer to the identified peripheral. In memory-to-memory mode, this field identifies the memory destination if DIR=1 and the memory source if DIR=0. In peripheral-to-peripheral mode, this field identifies the peripheral destination if DIR=1 and the peripheral source if DIR=0. Note: this field is set and cleared by software. It must not be written when the channel is enabled (EN = 1). It is read-only when the channel is enabled (EN=1)..

Allowed values:
0: Bits8: 8-bit size
1: Bits16: 16-bit size
2: Bits32: 32-bit size

MSIZE

Bits 10-11: memory size Defines the data size of each DMA transfer to the identified memory. In memory-to-memory mode, this field identifies the memory source if DIR=1 and the memory destination if DIR=0. In peripheral-to-peripheral mode, this field identifies the peripheral source if DIR=1 and the peripheral destination if DIR=0. Note: this field is set and cleared by software. It must not be written when the channel is enabled (EN = 1). It is read-only when the channel is enabled (EN=1)..

Allowed values:
0: Bits8: 8-bit size
1: Bits16: 16-bit size
2: Bits32: 32-bit size

PL

Bits 12-13: priority level Note: this field is set and cleared by software. It must not be written when the channel is enabled (EN = 1). It is read-only when the channel is enabled (EN=1)..

Allowed values:
0: Low: Low priority
1: Medium: Medium priority
2: High: High priority
3: VeryHigh: Very high priority

MEM2MEM

Bit 14: memory-to-memory mode Note: this bit is set and cleared by software. It must not be written when the channel is enabled (EN = 1). It is read-only when the channel is enabled (EN=1)..

Allowed values:
0: Disabled: Memory to memory mode disabled
1: Enabled: Memory to memory mode enabled

NDT

Bits 0-15: number of data to transfer (0 to 216-1) This field is updated by hardware when the channel is enabled: It is decremented after each single DMA 'read followed by write' transfer, indicating the remaining amount of data items to transfer. It is kept at zero when the programmed amount of data to transfer is reached, if the channel is not in circular mode (CIRC=0 in the DMA_CCRx register). It is reloaded automatically by the previously programmed value, when the transfer is complete, if the channel is in circular mode (CIRC=1). If this field is zero, no transfer can be served whatever the channel status (enabled or not). Note: this field is set and cleared by software. It must not be written when the channel is enabled (EN = 1). It is read-only when the channel is enabled (EN=1)..

Allowed values: 0x0-0xffff

PA

Bits 0-31: peripheral address It contains the base address of the peripheral data register from/to which the data will be read/written. When PSIZE[1:0]=01 (16 bits), bit 0 of PA[31:0] is ignored. Access is automatically aligned to a half-word address. When PSIZE=10 (32 bits), bits 1 and 0 of PA[31:0] are ignored. Access is automatically aligned to a word address. In memory-to-memory mode, this register identifies the memory destination address if DIR=1 and the memory source address if DIR=0. In peripheral-to-peripheral mode, this register identifies the peripheral destination address DIR=1 and the peripheral source address if DIR=0. Note: this register is set and cleared by software. It must not be written when the channel is enabled (EN = 1). It is not read-only when the channel is enabled (EN=1)..

MA

Bits 0-31: peripheral address It contains the base address of the memory from/to which the data will be read/written. When MSIZE[1:0]=01 (16 bits), bit 0 of MA[31:0] is ignored. Access is automatically aligned to a half-word address. When MSIZE=10 (32 bits), bits 1 and 0 of MA[31:0] are ignored. Access is automatically aligned to a word address. In memory-to-memory mode, this register identifies the memory source address if DIR=1 and the memory destination address if DIR=0. In peripheral-to-peripheral mode, this register identifies the peripheral source address DIR=1 and the peripheral destination address if DIR=0. Note: this register is set and cleared by software. It must not be written when the channel is enabled (EN = 1). It is not read-only when the channel is enabled (EN=1)..
