*: Reset if the status of V
DD
= 0.8 to 2.2 V lasts for 1 ms or longer. Program hang-up does not occur even if the
voltage drops, until the reset function is effected (when the RESET pin and WDOUT pin are connected). 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.
