8.4.1
The on-chip oscillator clock is supplied by the on-chip oscillator (low-speed on-chip oscillator).
The clock generated by the low-speed on-chip oscillator is used as the clock source for the CPU clock, and
peripheral function clock (fOCO-S, and fOCO128).
After a reset, the on-chip oscillator clock generated by the low-speed on-chip oscillator divided by 1 (no
division) is selected as the CPU clock.
If the XIN clock stops oscillating when bits OCD1 to OCD0 in the OCD register are set to 11b, the low-speed
on-chip oscillator automatically starts operating and supplies the necessary clock for the MCU.
The frequency of the low-speed on-chip oscillator varies depending on the supply voltage and the operating
ambient temperature. Application products must be designed with sufficient margin to allow for frequency
changes.
