Table IV. ADCCON2 SFR Bit Designations
Bit
Name
Description
ADCCON2.7 ADCI
The ADC interrupt bit (ADCI) is set by hardware at the end of a single ADC conversion cycle or at
the end of a DMA block conversion. ADCI is cleared by hardware when the PC vectors to the ADC Inter-
rupt Service Routine. Otherwise, the ADCI bit should be cleared by user code.
ADCCON2.6 DMA
The DMA mode enable bit (DMA) is set by the user to enable a preconfigured ADC DMA mode opera-
tion. A more detailed description of this mode is given in the ADC DMA Mode section. The DMA bit is
automatically set to “0” at the end of a DMA cycle. Setting this bit causes the ALE output to cease, it will
start again when DMA is started and will operate correctly after DMA is complete.
ADCCON2.5 CCONV
The continuous conversion bit (CCONV) is set by the user to initiate the ADC into a continuous mode of
conversion. In this mode, the ADC starts converting based on the timing and channel configuration
already set up in the ADCCON SFRs; the ADC automatically starts another conversion once a previ-
ous conversion has completed.
ADCCON2.4 SCONV
The single conversion bit (SCONV) is set to initiate a single conversion cycle. The SCONV bit is
automatically reset to “0” on completion of the single conversion cycle.
ADCCON2.3 CS3
The channel selection bits (CS3-0) allow the user to program the ADC channel selection under
ADCCON2.2 CS2
software control. When a conversion is initiated, the channel converted will be the one pointed to by
ADCCON2.1 CS1
these channel selection bits. In DMA mode, the channel selection is derived from the channel ID
ADCCON2.0 CS0
written to the external memory.
