(2) 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 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 05H.
Address: FFA4H
Symbol
OSTS
Remark f
Cautions 1. To set the STOP mode when the X1 clock is used as the CPU clock, set OSTS

while the internal high-speed oscillation clock is being used as the CPU clock,
set the oscillation stabilization time as follows.
Note, therefore, that only the status up to the oscillation stabilization time set by
