Reset Actions
Term Reset Action
NONE Register cannot be reset. Applies to read-only registers.
ARST Auxiliary Reset: registers are reset when the system powers up with standby power, and is never altered
by hardware again. Software writes are preserved.
CRST Control Reset: registers are not reset except under exceptional situations, such as power cycles or
watchdog timeout.

requested.

reset lines for each reset source.
