Channel Data 0–7
Reading the current ADC sample of a channel (0-7) is possible via these registers. For this, the channel must
be enabled in the corresponding Channel Configuration register (CHEN), since otherwise the read value will
always be zero (0x0).
The intention of this register interface is more a static evaluation of the input data, e.g. channel calibration.
The channel data is subdued a sign extension for both ADC operating modes (2’s complement and offset
binary output format).

The value read from such a register cannot be the last that has been sampled due to the AD
Converter 5-stage internal pipeline.
