(3) Description of registers
(a) Watch prescaler control register (WPCR)
[Bit 7] WIF: Watch interrupt flag
When writing, this bit is used to clear the watch interrupt flag.
When reading, this bit indicates that the watch interrupt has 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.
[Bit 2] WS1: Interrupt interval time specification bit by watch
[Bit 1] WS0: Interrupt interval time specification bit by watch
These bits are used to specify the interrupt cycles.
[Bit 0] WCLR: Bit clearing watch prescaler
This bit is used to clear the watch prescaler.
1 is always read when this bit is read.
