Set the PRC0 bit in the PRCR register to 1 (write enabled) before rewriting the FRA3 register.
Also, rewrite the FRA3 register when the FRA00 bit in the FRA0 register is set 0 (high-speed on-chip oscillator
off).

The frequency can be adjusted by transferring this value to the FRA1 register and by
transferring the correction value in the FRA5 register to the FRA3 register.
The frequency can be adjusted by transferring this value to the FRA3 register and by
transferring the correction value in the FRA4 register to the FRA1 register.
The frequency can be adjusted by transferring this value to the FRA1 register and by
transferring the correction value in the FRA7 register to the FRA3 register.
