2.8.2
When the RES input goes low all current processing stops and the CPU enters the reset state. All
interrupts are masked in the reset state. Reset exception handling starts when the RES signal
changes from low to high.
The reset state can also be entered by a watchdog timer overflow. For details, refer to section 11,
Watchdog Timer.
Notes: 1.

Reset State
2.
Bus-released state
From any state except hardware standby mode, a transition to the reset state occurs whenever RES
goes low. A transition can also be made to the reset state when the watchdog timer overflows.
From any state, a transition to hardware standby mode occurs when STBY goes low.
