compensates for the power oscillation period caused by momentary power
supply oscillations.
Specified at 4.5V for 5-volt operation, and at 2.7V for 3-volt operation.
If the above electrical conditions are not satisfied, the internal reset circuit will not
operate normally. In this case, initialized by instruction. (Refer to the Initializing by
Instruction section.)
