RESET:
The following equation calculates the PIT period when a fast reference frequency is
used:
The following equation calculates the PIT period for an externally input clock
frequency on both slow and fast reference frequency devices.
1. This register is shown with a read value.
This register can be read or written at any time. Bits [15:8] are unimplemented and will
always read zero.
To reset the software watchdog:
Both writes must occur in the order specified before the software watchdog times out,
but any number of instructions can occur between the two writes.
1. Write $55 to SWSR.
2. Write $AA to SWSR.
