RESET:
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.
