7.10 Edge Detection Function
The interrupt input pins (INTP0, INTP1, NMI/INTP2, INTP3 to INTP6) are used not only to input interrupt requests
but also to input trigger signals to the internal hardware units. Because these pins operate at an edge of the input
signal, they have a function to detect an edge. Moreover, a noise elimination function is also provided to prevent
erroneous detection due to noise.

7.11 Watch Timer
The watch timer has the following functions:
Watch timer
Interval timer
The watch timer and interval timer functions can be used at the same time.
(1) Watch timer
The watch timer sets the WTIF flag of the interrupt control register (WTIC) at time intervals of 0.5 seconds by
using the 32.768 kHz subsystem clock.
(2) Interval timer
The interval timer generates an interrupt request (INTTM3) at predetermined time intervals.
