RESET:
SYPCR controls system monitor functions, software watchdog clock prescaling, and
bus monitor timing. This register can be written once following power-on or reset.
This field selects software watchdog time-out period.
This field selects bus monitor time-out period.
0 = Software watchdog disabled
1 = Software watchdog enabled
0 = Software watchdog clock not prescaled
1 = Software watchdog clock prescaled by 512
0 = Disable halt monitor function
1 = Enable halt monitor function
0 = Disable bus monitor function for an internal to external bus cycle.
1 = Enable bus monitor function for an internal to external bus cycle.
