Debug Control Block
Implementations
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.
Disables TRACE. See DCB::enable_trace()
for more details
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.”
Pointer to the register block
Returns a pointer to the register block (to be deprecated in 0.7)
