t OFF ≥1 ms

Notes: 1. t OFF compensates for the power oscillation period caused by momentary power

supply oscillations.

2. Specified at 4.5V for standard voltage operation, and at 2.7V for low voltage operation.

3. If the above electrical conditions are not satisfied, the internal reset circuit will not

operate normally. In this case, the LSI must be initialized by software. (Refer to the

Initializing by Instruction section.)
