(2) Oscillation stabilization time select register (OSTS)
This register is used to select the high-speed system clock oscillation stabilization wait time when STOP mode is
released. The wait time set by OSTS is valid only after STOP mode is released when the high-speed system
clock is selected as the CPU clock. After STOP mode is released when the internal oscillation clock is selected,
check the oscillation stabilization time using OSTC.
OSTS can be set by an 8-bit memory manipulation instruction.
RESET input sets OSTS to 05H.
Cautions 1. To set the STOP mode when the high-speed system clock is used as the CPU clock, set

used as the CPU clock, set the oscillation stabilization time as follows.
The oscillation stabilization time counter counts only during the oscillation stabilization
time set by OSTS. Therefore, note that only the statuses during the oscillation stabilization
time set by OSTS are set to OSTC after STOP mode has been released.
