In the following cases, set the oscillation stabilization time of OSTS to the value
greater than the count value which is to be checked by the OSTC register after the
oscillation starts.

oscillation clock is being used as the CPU clock with the X1 clock oscillating.
(Note, therefore, that only the status up to the oscillation stabilization time set by
OSTS is set to OSTC after the STOP mode is released.)
