PRODUCTION DATA
The ADC can be triggered externally by the falling edge of the external trigger CNVT, or internally by writing to the ICONV bit in AFE Configuration Register 0. The ADC channel registers specify which external analog channel is converted.
When a new trigger activates, the ADC stops any existing conversion immediately and starts a new cycle. For example, the ADC is programmed to sample channel 0 to channel 3 repeatedly (auto-mode). During the conversion of channel 1, an external trigger is activated. The ADC stops converting channel 1 immediately and starts converting channel 0 again, instead of proceeding to convert channel 2.
