0.1 ms ≤ t _rcc ≤ 10 ms
t OFF *1
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.)
