Comparator A–D Value Registers (CMPA–CMPD)
Note:
These registers are unaffected by reset.
23.6.3
Exception Cause Register (ECR)
The ECR indicates the cause of entry into debug mode. All bits are set by the hardware and cleared when
the register is read when debug mode is disabled, or if the processor is in debug mode. Attempts to write
to this register are ignored. When the hardware sets a bit in this register, debug mode is entered only if
debug mode is enabled and the corresponding mask bit in the DER is set.
All bits are cleared to zero following reset.
