Debug Control Block
Implementations§
source§impl DCB
impl DCB
sourcepub fn enable_trace(&mut self)
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.
sourcepub fn disable_trace(&mut self)
pub fn disable_trace(&mut self)
Disables TRACE. See DCB::enable_trace()
for more details
sourcepub fn is_debugger_attached() -> bool
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.”
