(5) Oscillation stabilization time select register (OSTS)
This register is used to select the X1 clock oscillation stabilization wait time when the STOP mode is released.
When the X1 clock is selected as the CPU clock, the operation automatically waits for the time set using the OSTS
register after the STOP mode is released.
When the high-speed on-chip oscillator clock is selected as the CPU clock, confirm with the oscillation stabilization
time counter status register (OSTC) that the desired oscillation stabilization time has elapsed after the STOP mode is
released. The oscillation stabilization time can be checked up to the time set using the OSTC register.
The OSTS register can be set by an 8-bit memory manipulation instruction.
Reset signal generation sets the OSTS register to 07H.
