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 reset state occurs when RES is
driven low.
From any state, a transition to hardware standby mode occurs when STBY is driven low.
