8.3 Watch Timer Control Register
(1) Watch timer mode control register (WTM)
210
The watch timer mode control register (WTM) controls the watch timer.
This register enables or disables the count clock and operation of the watch timer, sets the interval time of the
prescaler, controls the operation of the 5-bit counter, and sets the interrupt time of the watch timer.
WTNM is set by a 1-bit or 8-bit memory manipulation instruction.
RESET input clears WTM to 00H.
