An internal high-speed oscillator is incorporated in the
After a reset release, the internal high-speed oscillator automatically starts oscillation (16 MHz (TYP.)).
An internal low-speed oscillator is incorporated in the
The internal low-speed oscillation clock is only used as the watchdog timer and the clock of 8-bit timer H1. The
