Note 1. Chip-specific value
HOCOTRR0 corresponds to 32 MHz.
HOCOTRD[5:0] Bits (High-Speed On-Chip Oscillator Frequency Adjustment)
Set the frequency adjustment value for the high-speed on-chip oscillator.
The setting range is from 0 (00h) to 63 (3Fh) by binary numbers. The greater the set value is, the higher the frequency is.
The frequency is adjusted under certain conditions before shipment, so the value after reset varies with the chip. After a
reset, the oscillation frequency returns to the factory default.
