Calibration is Done (read only)
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.
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.
