VOLTAGE DROP DETECTION CIRCUIT
The built-in voltage drop detection circuit is designed to detect a
drop in voltage and to reset the microcomputer if the supply
voltage drops below a set value.

The microcomputer starts operation
after the f(XIN) is counted 10757 to
10786 times.
Note: Set the VDCE pin to “H” level to operate the
voltage drop detection circuit.
The voltage drop detection circuit is not operated at the RAM
back-up mode.
