7.2 Standby Function Control Register
The oscillation stabilization time selection register (OSTS) is used to control the wait time from the time STOP
mode is released by an interrupt request until oscillation stabilizes.
OSTS is set using an 8-bit memory manipulation instruction.
RESET input sets this register to 04H. Note that the time required for oscillation to stabilize after RESET input or
the release of STOP mode by POC will be taken as the time selected by mask option (2
15/fX, or 217/fX) (refer to 9.
MASK OPTION for mask option details) .

Caution
The wait time required after releasing STOP mode does not include the time (“a” in the following
figure) required for the clock oscillation to restart after STOP mode is released, regardless of
whether STOP mode is released by RESET input or interrupt.
