This calibration should be used when the RC8M is used at a frequency of 1 MHz and when the voltage of the VDDIN_5 pin is
within [4.5V:5.5V]. This value should be written to RCCR8.CALIB field of the SCIF module.
This calibration should be used when the RC8M is used at a frequency of 8 MHz and when the voltage of the VDDIN_5 pin is
within [4.5V:5.5V]. This value should be written to RCCR8.CALIB.
This calibration should be used when the RC8M is used at a frequency of 1 MHz and when the voltage of the VDDIN_5 pin is
within [3.0V:3.6V]. This value should be written to RCCR8.CALIB.
This calibration should be used when the RC8M is used at a frequency of 8 MHz and when the voltage of the VDDIN_5 pin is
within [3.0V:3.6V]. This value is automatically loaded in RCCR8.CALIB at power-up.
