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. 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.
