Note
Reset if the status of VDD = 2.05 V (TYP.) 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.
