Analog-to-Digital Converter (ADC)
15.8.1 ADC Status and Control Register
Data Sheet
242
Address:
Function of the ADC status and control register is described here.
COCO — Conversions Complete Bit
AIEN — ADC Interrupt Enable Bit
ADCO — ADC Continuous Conversion Bit
Reset:
Read:
Write:
When the AIEN bit is a logic 0, the COCO is a read-only bit which is
set each time a conversion is completed. This bit is cleared whenever
the ADSCR is written, or whenever the ADC clock control register is
written, or whenever the ADC data register low, ADRLx, is read.
If the AIEN bit is logic 1, the COCO bit always read as logic 0. ADC
interrupt will be generated at the end if an ADC conversion. Reset
clears the COCO bit.
When this bit is set, an interrupt is generated at the end of an ADC
conversion. The interrupt signal is cleared when the data register,
ADR0, is read or the ADSCR is written. Reset clears the AIEN bit.
When set, the ADC will convert samples continuously and update the
ADC data register at the end of each conversion. Only one conversion
is allowed when this bit is cleared. Reset clears the ADCO bit.
This bit should not be set when auto-scan mode is enabled; i.e. when
ASCAN=1.

1 = Conversion completed (AIEN = 0)
0 = Conversion not completed (AIEN = 0)/CPU interrupt (AIEN=1)
1 = ADC interrupt enabled
0 = ADC interrupt disabled
1 = Continuous ADC conversion
0 = One ADC conversion
