The clock fC4 is used for timer RE and the clock fC32 is used for timer RA.
Use fC4 and fC32 while the XCIN clock oscillation stabilizes.
(For J, K version, fC4 and fC32 cannot be used.)
fOCO128 is generated by fOCO divided by 128.
The clock fOCO128 is used for capture signal of timer RC’s TRCGRA register.
