SDATA_IN: Slot 4 – PCM Record Right Channel
This slot contains sampled data from the right channel of the
stereo ADC. The signal to be digitized is selected using the
Record Select register (1Ah) and subsequently routed
through the Record Select Mux and the Record Gain ampli-
fier to the ADC.
This is a 20-bit slot and the digitized 18-bit PCM data is
transmitted in an MSB justified format. The remaining 2
LSBs are stuffed with zeros.
