Section 3 Processing States
3.2
When the RES input goes low all current processing stops and the CPU enters 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 the relevant
microcontroller hardware manual.

2.
Bus-released state
From any state except hardware standby mode, a transition to the reset state occurs whenever RES
goes low.
From any state, a transition to hardware standby mode occurs when STBY goes low.
