RESET output (Detection of 2.15 V)

The

RESET outputs a signal to prevent the microcomputer from malfunctioning due to a drop in supply voltage.

When powering up,

RESET is kept at low level until the supply voltage reaches V

The

RESET output has a large hysteresis voltage of approximately 2 V between the rise in supply voltage at power-

up and its fall.
