9.2.2 Operation in Stop mode
In Stop mode, Watchdog timer stops operating. Immediately after Stop mode is terminated, Watchdog timer
operates as follows.
9.2.3 Operation in Hold state
Watchdog timer stops operating in Hold state. When Hold state is terminated, Watchdog timer restarts
counting in the same state where it stopped operating.
Hold state : Refer to section “12.4 Hold function.”
