PRODUCTION DATA
Two types of ADC conversion modes are available: direct and auto. The conversion mode (CMODE) bit of the AFE Configuration 0 register specifies the conversion mode.
In direct mode, each analog channel within the specified group is converted a single time. After the last channel is converted, the ADC enters an idle state and waits for a new trigger.
Auto mode is a continuous operation. In auto mode, each analog channel within the specified group is converted sequentially and repeatedly.
The flow chart of the ADC conversion sequence in Figure 7-18 shows the conversion process.
The current conversion cycle stops immediately if:
When a new external or internal trigger activates, the ADC starts a new conversion cycle. Do not issue the internal trigger at the same time the conversion mode is changed. If a 1 is simultaneously written to the ICONV bit when changing the CMODE bit to 0 or 1, the current conversion stops and immediately returns to the wait for ADC trigger state.
