Chapter 34 Analog-to-Digital Converter (ADC)
Writing SC1A while SC1A is actively controlling a conversion aborts the current
conversion. In software trigger mode (ADTRG=0), writes to the SC1A register
subsequently initiate a new conversion (if the ADCH bits are equal to a value other than
all 1s).
Similarly, writing any of the SC1n registers while that specific SC1n register is actively
controlling a conversion aborts the current conversion. None of the SC1B-SC1n registers
are used for software trigger operation and therefore writes to the SC1B - SC1n registers
do not initiate a new conversion.
Addresses: ADC0_SC1A is 4003_B000h base + 0h offset = 4003_B000h
ADC0_SC1B is 4003_B000h base + 4h offset = 4003_B004h
ADC1_SC1A is 400B_B000h base + 0h offset = 400B_B000h
ADC1_SC1B is 400B_B000h base + 4h offset = 400B_B004h

ADCx_SC1n field descriptions
Description
This read-only field is reserved and always has the value zero.
Conversion complete flag
The COCO flag is a read-only bit that is set each time a conversion is completed when the compare
function is disabled (ACFE=0) and the hardware average function is disabled (AVGE=0). When the
compare function is enabled (ACFE=1), the COCO flag is set upon completion of a conversion only if the
compare result is true. When the hardware average function is enabled (AVGE=1), the COCO flag is set
upon completion of the selected number of conversions (determined by the AVGS bits). The COCO flag in
SC1A is also set at the completion of a Calibration sequence. The COCO bit is cleared when the
respective SC1n register is written or when the respective Rn register is read.
0 Conversion not completed.
1 Conversion completed.
