Figure 2−5. Recommended Procedure for Issuing SAP Configuration Updates
Figure 2−6, Figure 2−7, and Figure 2−8 tabularize the formatting and word size options available for the input SAP
and output SAP. In these figures, data formats are paired when the only difference between the pair is whether the
word placement within the LRCLK period is left justified or I

S. The TDM formats available include single chip TDM
output formats (SDOUT1
chipA
or SDOUT1
chipB
) and two chip TDM output formats (SDOUT1
chipA
OR’ed with
SDOUT1
chipB
). For two chip TDM output formats, the OR’ing operation is accomplished by routing SDOUT1 from
one of the two TAS3103 chips to ORIN of the other TAS3103 chip. The AB bit also comes into play for two chip TDM
formats; AB must be set to 1 on one of the two TAS3103 chips and set to 0 on the other TAS3103 chip. For a given
connection of SDOUT1 to ORIN, it does not matter which TAS3103 is set up as chip AB = 1 and which chip is set
up as chip AB = 0. However, the routing of the processed data to the output registers in the TAS3103 is dependent
on which chip is chip AB = 0 and which chip is chip AB = 1. Figure 2−10 and Figure 2−11 illustrate this dependence.
