PRODUCTION DATA
DAV is an output pin that indicates the completion of ADC conversions. The DAVF bit in AFE configuration register 0 determines the status of the DAV pin. In direct mode, after the selected group of input channels are converted and the ADC is stopped, the DAVF bit is set to 1 and the DAV pin is driven to logic low (active). In ADC auto mode, each time the group of input channels are sequentially converted, a 1-µs pulse (low) appears on the DAV pin.
