Watchdog Interrupt Priority. This bit controls the priority of the watchdog interrupt.
bit 4
0 = The watchdog interrupt is low priority.
1 = The watchdog interrupt is high priority.
PX5
External Interrupt 5 Priority. This bit controls the priority of external interrupt 5.
bit 3
0 = External interrupt 5 is low priority.
1 = External interrupt 5 is high priority.
PX4
External Interrupt 4 Priority. This bit controls the priority of external interrupt 4.
bit 2
0 = External interrupt 4 is low priority.
1 = External interrupt 4 is high priority.
PX3
External Interrupt 3 Priority. This bit controls the priority of external interrupt 3.
bit 1
0 = External interrupt 3 is low priority.
1 = External interrupt 3 is high priority.
PX2
External Interrupt 2 Priority. This bit controls the priority of external interrupt 2.
bit 0
0 = External interrupt 2 is low priority.
1 = External interrupt 2 is high priority.

This system clock is divided by the value of the 16-bit register MSECH:MSECL. Then, that 1ms timer tick is divided by the
register HMSEC which provides the 100ms signal used by this seconds timer. Therefore, this seconds timer can generate
an interrupt which occurs from 100ms to 12.8 seconds. Reading this register will clear the Seconds Interrupt. This Interrupt
can be monitored in the AIE register.
WRT
Write Control. Determines whether to write the value immediately or wait until the current count is finished.
bit 7
Read = 0.
0 = Delay Write Operation. The SEC value is loaded when the current count expires.
1 = Write Immediately. The counter is loaded once the CPU completes the write operation.
SECINT60 Seconds Count. Normal operation would use 100ms as the clock interval.
bits 60
Seconds Interrupt = (1 + SEC)
(HMSEC + 1) (MSEC + 1) tCLK.
