10.4 Watch Timer Operations

10.4.1 Watch timer operation

The watch timer generates an interrupt request signal (INTWT) at a specific time interval by using the peripheral

hardware clock or subsystem clock.

When bit 0 (WTM0) and bit 1 (WTM1) of the watch timer operation mode register (WTM) are set to 1, the count

operation starts. When these bits are cleared to 0, the 5-bit counter is cleared and the count operation stops.

When the interval timer is simultaneously operated, zero-second start can be achieved only for the watch timer by

clearing WTM1 to 0. In this case, however, the 11-bit prescaler is not cleared. Therefore, an error up to 2

1/f

seconds occurs in the first overflow (INTWT) after zero-second start.

The interrupt request is generated at the following time intervals.

10.4.2 Interval timer operation

The watch timer operates as interval timer which generates interrupt request signals (INTWTI) repeatedly at an

interval of the preset count value.

The interval time can be selected with bits 4 to 6 (WTM4 to WTM6) of the watch timer operation mode register

(WTM).

When bit 0 (WTM0) of the WTM is set to 1, the count operation starts. When this bit is set to 0, the count operation

stops.
