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.

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, PDTA = 0, DEL = 0, MUEN = 0
4-bit data samples continuously written to SSITDR are transmitted onto the serial audio bus.
As basic sample format configuration except SCKP = 1
