When releasing a reset (above figure) or releasing STOP mode while the CPU is operating on the internal
high-speed oscillation clock, confirm the oscillation stabilization time for the X1 clock using the oscillation
stabilization time counter status register (OSTC). If the CPU operates on the high-speed system clock (X1
