compensates for the power oscillation period caused by momentary power supply
oscillations.
Specified at 4.5 V for 5-V operation, and at 2.7 V for 3-V operation.
For if 4.5 V is not reached during 5-V operation, 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.)
