0xE000101C
Offset:
0x1C
Retention:
Retained
IsDeepSleep:
No
Comment:
Samples the current value of the program counter. Unless DWT_PCSR reads as
0xFFFFFFFF, under the conditions described in Program counter sampling support on Arm
TRM page C1-344, bit [0] is RAZ. When RAZ, bit [0] does not reflect instruction set state as is
the case with similar functionality in
other ARM architecture profiles.
Default:
0x0
