(3) Oscillation stabilization time select register (OSTS)
The wait time until the oscillation stabilizes after the STOP mode is released or the wait time until the on-chip flash
memory stabilizes after the IDLE2 mode is released is controlled by the OSTS register.
The OSTS register can be read or written 8-bit units.
Reset sets this register to 06H.
Note The oscillation stabilization time and setup time are required when the STOP mode and
