Reset if the status of V
DD
= 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. Some oscillators stop oscillating before the reset
function is effected.
Remark
The region indicated by the broken line in the above figure is the guaranteed operating range in the high-
speed mode.
