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 I2S. The TDM formats available include single-chip TDM

output formats (SDOUT1chipA or SDOUT1chipB) and two-chip TDM output formats (SDOUT1chipA ORed with

SDOUT1chipB). For two-chip TDM output formats, the ORing operation is accomplished by routing SDOUT1 from one

of the two TAS3103A chips to ORIN of the other TAS3103A chip. The AB bit also comes into play for two-chip TDM

formats; AB must be set to 1 on one of the two TAS3103A chips and set to 0 on the other TAS3103A chip. For a given

connection of SDOUT1 to ORIN, it does not matter which TAS3103A 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 TAS3103A depends on

which chip is chip AB = 0 and which chip is chip AB = 1. Figure 2−10 and Figure 2−11 illustrate this dependence.
