There are some extend format of the Philips' specification that allows more than 2 channels to be
transferred within two system words.
The SSI module supports the transfer of 4, 6 and 8 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 26.5 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.
