There are several more configuration bits in non-compressed mode which will now be
demonstrated. These bits are NOT mutually exclusive, however some configurations will probably
not be useful for any other device.
They are demonstrated by referring to the following basic sample format shown in figure 26.9.
In figure 26.9, system word length of 6 bits and a data word length of 4 bits are used. Neither of
these are possible with the SSI module but are used only for clarification of the other
configuration bits.

SSI_WS
SSI_SDATA
SWL = 6 bits (not attainable in SSI module, demonstration only)
DWL = 4 bits (not attainable in SSI module, demonstration only)
CHNL = 00, SCKP = 0, SWSP = 0, SPDP = 0, SDTA = 0, PDATA = 0, DEL = 0, MUEN = 0
4-bit data samples continuously written to SSITDR are transmitted onto the serial audio bus.
