Manual
When a transition is made between modes by means of an interrupt, the transition cannot be
made on interrupt source generation alone. Ensure that interrupt handling is performed after
accepting the interrupt request.
From any state except hardware standby mode, a transition to the power-on reset state occurs
when RES is driven low. From any state except hardware standby mode and power-on reset, a
transition to the manual reset state occurs when MRES is driven low.
From any state, a transition to hardware standby mode occurs when STBY is driven low.
Always select high-speed mode before making a transition to watch mode or subactive mode.
