Implementations§
§impl DWT
impl DWT
pub fn num_comp() -> u8
pub fn num_comp() -> u8
Number of comparators implemented
A value of zero indicates no comparator support.
pub fn has_exception_trace() -> bool
armv6m only.
pub fn has_exception_trace() -> bool
armv6m only.Returns true if the the implementation supports sampling and exception tracing
pub fn has_external_match() -> bool
armv6m only.
pub fn has_external_match() -> bool
armv6m only.Returns true if the implementation includes external match signals
pub fn has_cycle_counter() -> bool
armv6m only.
pub fn has_cycle_counter() -> bool
armv6m only.Returns true if the implementation supports a cycle counter
pub fn has_profiling_counter() -> bool
armv6m only.
pub fn has_profiling_counter() -> bool
armv6m only.Returns true if the implementation the profiling counters
pub fn enable_cycle_counter(&mut self)
armv6m only.
pub fn enable_cycle_counter(&mut self)
armv6m only.Enables the cycle counter
The global trace enable (DCB::enable_trace) should be set before
enabling the cycle counter, the processor may ignore writes to the
cycle counter enable if the global trace is disabled
(implementation defined behaviour).
pub fn disable_cycle_counter(&mut self)
armv6m only.
pub fn disable_cycle_counter(&mut self)
armv6m only.Disables the cycle counter
pub fn cycle_counter_enabled() -> bool
armv6m only.
pub fn cycle_counter_enabled() -> bool
armv6m only.Returns true if the cycle counter is enabled
pub fn get_cycle_count() -> u32
cycle_count which follows the C-GETTER conventionAvailable on non-armv6m only.
pub fn get_cycle_count() -> u32
cycle_count which follows the C-GETTER conventionarmv6m only.Returns the current clock cycle count
pub fn cycle_count() -> u32
armv6m only.
pub fn cycle_count() -> u32
armv6m only.Returns the current clock cycle count
pub fn set_cycle_count(&mut self, count: u32)
armv6m only.
pub fn set_cycle_count(&mut self, count: u32)
armv6m only.Set the cycle count
pub fn unlock()
armv6m only.
pub fn unlock()
armv6m only.Removes the software lock on the DWT
Some devices, like the STM32F7, software lock the DWT after a power cycle.
pub fn cpi_count() -> u8
armv6m only.
pub fn cpi_count() -> u8
armv6m only.Get the CPI count
Counts additional cycles required to execute multi-cycle instructions,
except those recorded by lsu_count, and counts any instruction fetch
stalls.
pub fn set_cpi_count(&mut self, count: u8)
armv6m only.
pub fn set_cpi_count(&mut self, count: u8)
armv6m only.Set the CPI count
pub fn exception_count() -> u8
armv6m only.
pub fn exception_count() -> u8
armv6m only.Get the total cycles spent in exception processing
pub fn set_exception_count(&mut self, count: u8)
armv6m only.
pub fn set_exception_count(&mut self, count: u8)
armv6m only.Set the exception count
pub fn sleep_count() -> u8
armv6m only.
pub fn sleep_count() -> u8
armv6m only.Get the total number of cycles that the processor is sleeping
ARM recommends that this counter counts all cycles when the processor is sleeping, regardless of whether a WFI or WFE instruction, or the sleep-on-exit functionality, caused the entry to sleep mode. However, all sleep features are implementation defined and therefore when this counter counts is implementation defined.
pub fn set_sleep_count(&mut self, count: u8)
armv6m only.
pub fn set_sleep_count(&mut self, count: u8)
armv6m only.Set the sleep count
pub fn lsu_count() -> u8
armv6m only.
pub fn lsu_count() -> u8
armv6m only.Get the additional cycles required to execute all load or store instructions
pub fn set_lsu_count(&mut self, count: u8)
armv6m only.
pub fn set_lsu_count(&mut self, count: u8)
armv6m only.Set the lsu count
pub fn fold_count() -> u8
armv6m only.
pub fn fold_count() -> u8
armv6m only.Get the folded instruction count
Increments on each instruction that takes 0 cycles.
pub fn set_fold_count(&mut self, count: u8)
armv6m only.
pub fn set_fold_count(&mut self, count: u8)
armv6m only.Set the folded instruction count
