WATCH

PRESCALER

[Bit 7] WIF: Watch interrupt flag
When writing, this bit is used to clear the watch interrupt flag.

Clears watch interrupt flag

No operation

When reading, this bit indicates that the watch interrupt has occurred.

Watch interrupt not occurred

Watch interrupt occurred

1 is read when the Read Modify Write instruction is read. If the WIF bit is set
to 1 when the WIE bit is 1, an interrupt request is output. This bit is cleared
upon reset.

[Bit 6] WIE: Watch interrupt enable bit
This bit is used to enable an interrupt by the watch.

Interrupt by watch disabled

Interrupt by watch enabled

[Bit 1 and 0] WS1, WS0: Interrupt interval time specification bit by watch
These bits are used to specify the interrupt cycles.

31.25 ms

0.25 s

0.50 s

1.00 s

WS1

WS0

Interrupt cycle

: Subclock oscillation frequency

Value at f

= 32.768 kHz

[Bit 0] WCLR: Bit clearing watch prescaler
This bit is used to clear the watch prescaler.

Watch prescaler cleared

No operation

1 is always read when this bit is read.
