Struct stm32_hal2::pac::DCB [−][src]
pub struct DCB { /* fields omitted */ }Debug Control Block
Implementations
impl DCB[src]
impl DCB[src]pub fn enable_trace(&mut self)[src]
Enables TRACE. This is for example required by the
peripheral::DWT cycle counter to work properly.
As by STM documentation, this flag is not reset on
soft-reset, only on power reset.
pub fn disable_trace(&mut self)[src]
Disables TRACE. See DCB::enable_trace() for more details
pub fn is_debugger_attached() -> bool[src]
Is there a debugger attached? (see note)
Note: This function is reported not to work on Cortex-M0 devices. Per the ARM v6-M Architecture Reference Manual, “Access to the DHCSR from software running on the processor is IMPLEMENTATION DEFINED”. Indeed, from the Cortex-M0+ r0p1 Technical Reference Manual, “Note Software cannot access the debug registers.”
impl DCB[src]
impl DCB[src]pub const PTR: *const RegisterBlock[src]
Pointer to the register block
pub const fn ptr() -> *const RegisterBlock[src]
Returns a pointer to the register block (to be deprecated in 0.7)
