Reset 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.
The power-down state also includes watch mode, subactive mode, subsleep mode, etc. For details,
refer to section 26, Power-Down Modes.
