Reset state
Program execution state
Notes:
reset state
Manual
MRES = High
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 reset state occurs when RES is
driven low. From any state except hardware standby mode and power-on reset state, 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.
