Channel selection:
- “00”=Channel disabled,
- “01”=16-bit counter on clock ADCA,
- “10”=Channel A two’s complement encoding, i.e. samples go straight through
as ADCs output samples in two’s complement 14-bit format. 14-bit samples
coming from the ADC are extended to 16-bit on SHBA – Bit13 is copied onto
Bits14 and 15.
- “11”=Channel A binary encoding. Binary conversion consists in inverting the
MSB of each sample. This operation introduces a DC offset of half the full
scale, which can be removed by subtracting 8192 (decimal) of each sample.
