The oscillation stabilizing time is a period until the oscillation becomes stable after VDD becomes higher than minimum
operating voltage. (Refer to Figure4)

The oscillation stabilizing time is a period until the oscillation becomes stable after executing the instruction which starts the
sub-clock oscillation or after releasing the HOLD mode. (Refer to Figure4)
(Notes) Since the circuit pattern affects the oscillation frequency, place the oscillation-related parts as close to
the oscillation pins as possible with the shortest possible pattern length.
