CS49300 Family DSP
C - SCLK Polarity
D - FIFO Setup (only valid for parallel modes of
data delivery)
The following tables show the different values for
each parameter as well as the hex message that
needs to be sent. When creating the hardware
configuration message, only one hex message
should be sent per parameter. It should be noted
that the entire B parameter hex message must be
sent, even if one of the input ports has been defined
as unused by the A parameter.
