ADCREQ
ADC Request Enable—This bit controls
DMA requesting and interrupt
generation from an A/D conversion.
If this bit is set, an interrupt or DMA
request is generated when an A/D
conversion is available in the FIFO. If
this bit is cleared, no DMA request or
interrupt is generated following an A/D
conversion. To select a specific mode,
refer to Table 4-3 for available modes
and associated bit patterns.
