10.1 Functions
The watch timer has the following functions.
• Watch timer:
• Interval timer: An interrupt request signal (INTWTI) is generated at set intervals.
The watch timer and interval timer functions can be used at the same time.
Caution
INTWTI interrupt of the watch timer and INTRTC2 interrupt of RTC, and INTWT interrupt
of the watch timer and INTRTC0 interrupt of RTC are alternate interrupt signals, and
therefore cannot be used simultaneously. (
An interrupt request signal (INTWT) is generated at intervals of 0.5 or 0.25 seconds by using the
main clock or subclock.
