Operation stop time is 276 s (MIN.), 544 s (TYP.), and 1.074 ms (MAX.).
The clock oscillation stabilization time for default start is selected by the option byte. For details, refer
to CHAPTER 18 OPTION BYTE. The oscillation stabilization time that elapses after the STOP mode
is released is selected by the oscillation stabilization time select register (OSTS).
