is selected, none of the MA signals can be used for analog or digital inputs. They become multiplexed
address outputs and are unaffected by DDRQA[1:0].
28.7.2.2 Module Version Options
The number of available analog channels varies, depending on whether external multiplexing is used. A
maximum of eight analog channels are supported by the internal multiplexing circuitry of the converter.

chips.
28.7.3
This section describes the QADC analog subsystem, which includes the front-end analog multiplexer and
analog-to-digital converter.
28.7.3.1 Analog-to-Digital Converter Operation
The analog subsystem consists of the path from the input signals to the A/D converter block. Signals from
the queue control logic are fed to the multiplexer and state machine. The end-of-conversion (EOC) signal
and the successive approximation register (SAR) reflect the result of the conversion.

No External Mux
The external trigger inputs are not shared with two analog input signals.
When external multiplexing is used, two input channels are configured as multiplexed address
outputs, and for each external multiplexer chip, one input channel is a multiplexed analog input.
