Note: Set the PRCR.PRC0 bit to 1 (write enabled) before rewriting this register.
Note 1. Chip-specific value
LOCOTRD[4:0] Bits (Low-Speed On-Chip Oscillator Frequency Adjustment)
Set the frequency adjustment value for the low-speed on-chip oscillator.
The setting range is -16 (10h) to 15 (0Fh) by two's complements. 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.

Note 1. Chip-specific value
ILOCOTRD[4:0] Bits (IWDT-Dedicated On-Chip Oscillator Frequency Adjustment)
Set the frequency adjustment value for the IWDT-dedicated on-chip oscillator.
The setting range is from 0 (00h) to 31 (1Fh) 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.
