(3) Oscillation stabilization time select register (OSTS)
This register selects the oscillation stabilization time that elapses after the RESET signal is applied or the STOP
mode is released, until oscillation is stabilized.
OSTS is set by an 8-bit memory manipulation instruction.
RESET input sets this register to 04H. Therefore, to release the STOP mode by inputting the RESET signal,
the time required to release the mode is 2
