Section 34 Serial Sound Interface (SSI)

(6)
Some devices extend the definition of the specification by Philips and allow more than 2 channels
to be transferred within two system words.
The SSI module supports the transfer of 2, 3 and 4 channels by the use of the CHNL, SWL and
DWL bits. It is important that the system word length (SWL) is greater than or equal to the
number of channels (CHNL) times the data word length (DWL).
Table 34.5 shows the number of padding bits for each of the valid configurations. If a setup is not
valid it does not have a number in the following table and has instead a dash.
