1. For the high-speed on-chip oscillator, the correction value in the FRA4 register should be written into the FRA1
In UART mode, the bit rate is the frequency divided by the UiBRG (i = 0 or 1) register and divided by 16.
register and the correction value in the FRA5 register should be written into the FRA3 register.
This applies when the high-speed on-chip oscillator is selected as the system clock and bits FRA22 to FRA20
in the FRA2 register are set to 000b (divide-by-2 mode). For the precision of the high-speed on-chip oscillator,
