A/D Calibration Register
| CALEN | Self Calibration Enable 1 = Enable self calibration 0 = Disable self calibration Software can set this bit to 1 enables A/D converter to do self calibration function. It needs 127 ADC clocks to complete calibration. This bit must be kept at 1 after CALDONE asserted. Clearing this bit will disable self calibration function. |
| CALDONE | Calibration is Done 1 = A/D converter self calibration is done. 0 = A/D converter has not been calibrated or calibration is in progress if CALEN bit is set. When 0 is written to CALEN bit, CALDONE bit is cleared by hardware immediately. It is a read only bit. |
