CHAPTER 5 CLOCK GENERATOR
(4) 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 OSTS after
the STOP mode is released.
When the internal high-speed oscillation clock is selected as the CPU clock, confirm with 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 OSTC.
OSTS can be set by an 8-bit memory manipulation instruction.
Reset signal generation sets OSTS to 07H.
