fOCO-S is an operating clock for the voltage detection circuit.
This clock is generated by the low-speed on-chip oscillator and supplied by setting the CM14 bit to 0 (low-
speed on-chip oscillator on).
In wait mode, the fOCO-S clock does not stop.
fOCO128 is a clock generated by dividing fOCO-S or fOCO-F by 128. When the FRA03 bit is set to 0, fOCO-
S divided by 128 is selected. When this bit is set to 1, fOCO-F divided by 128 is selected.
fOCO128 is configured as the capture signal used in the TRCGRA register for timer RC.
fC, fC2, fC4, and fC32 are used for timers RA, RE, and the serial interface.
Use theses clocks while the XCIN clock oscillation stabilizes.
fOCO-WDT is an operating clock for the watchdog timer.
This clock is generated by the low-speed on-chip oscillator for the watchdog timer and supplied by setting the
CSPRO bit in the CSPR register to 1 (count source protect mode enabled).
In count source protection mode for the watchdog timer, the fOCO-WDT clock does not stop.
