RESET:
Bits in this register determine the function of port F pins. Setting a bit assigns the
corresponding pin to a control signal; clearing a bit assigns the pin to port F. Refer to
Table D-6.
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 bit controls the value of the software watchdog prescaler.
The reset value of SWP is the complement of the state of the MODCLK pin during
reset.
This field selects the divide ration used to establish software watchdog timeout period.
Refer to Table D-7.
0 = Software watchdog is disabled.
1 = Software watchdog is enabled.
0 = Software watchdog clock is not prescaled.
1 = Software watchdog clock is prescaled by 512.
