Watch Timer
The watch timer is a 15-bit free-run counter that counts up in synchronization with the subclock.
Eight different intervals can be selected, and interrupt requests generated for each interval time.
Supplies a timer for subclock oscillation stabilization standby, and an operational clock for the watchdog timer.
The subclock is always the count clock, regardless of the clock selection register (CKSCR) setting.
Interval timer feature
When the interval time set by the interval time selection bits (WTC : WTC2 to WTC0) is reached, the clock
timer generates an overflow in the bits corresponding to the interval time of the watch timer counter, and sets
the overflow flag bit (WTC : WTOF
= 1) .
Interrupts arising from overflows are enabled (WTC : WTIE
= 1) , an interrupt request is generated when the
overflow flag bit is set (WTC : WTOF
= 1) .
Select from one of the following 8 watch timer intervals :
