Note
Reset if the status of VDD = 1.7 to 2.0 V lasts for 1 ms or longer. Program hang-up does not occur even
if the voltage drops, until the reset function is effected. A resonator may stop oscillating before the reset
function is effected if normal operation under the low voltage is not guaranteed.
Caution Design the application circuit so that the RESET pin goes low when the supply voltage is less
than 2.2 V.
Remark
The region indicated by the broken lines in the above figure is the guaranteed operating range in the
high-speed mode.
