enabled (WTM.WTM1 and WTM.WTM0 bits = 1).
Some time is required before the first watch timer interrupt request signal (INTWT) is generated after operation is
Remarks 1. When 0.5 seconds of the watch timer interrupt time is set.
It takes 0.515625 seconds (max.) for the first INTWT signal to be generated (2
longer (max.)). The INTWT signal is then generated every 0.5 seconds.
