voltage detector, or input a low level to the RESET pin.
The internal high-speed oscillation clock and a high-speed system clock or subsystem clock can be
selected as the CPU clock. To use the X1 clock, use the OSTC register to confirm the lapse of the
oscillation stabilization time. To use the XT1 clock, use the timer function for confirmation of the lapse
of the stabilization time.
