Struct DCB

source
pub struct DCB { /* private fields */ }
Expand description

Debug Control Block

Implementations§

source§

impl DCB

source

pub fn enable_trace(&mut self)

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.

source

pub fn disable_trace(&mut self)

Disables TRACE. See DCB::enable_trace() for more details

source

pub fn is_debugger_attached() -> bool

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.”

source§

impl DCB

source

pub const PTR: *const RegisterBlock = {0xe000edf0 as *const peripheral::dcb::RegisterBlock}

Pointer to the register block

source

pub const fn ptr() -> *const RegisterBlock

👎Deprecated since 0.7.5: Use the associated constant PTR instead

Returns a pointer to the register block
