The tdata bus is zero padded to an 8-bit boundary. As this is an input, the pad bits are ignored.
The following diagrams show the format and example timing of tdata into the RELOAD channel. When multiple filter sets have been specified Transaction 0 defines the index of the filter set being reloaded (zero indexed). When a single filter set has been specified this field/transaction is not present in the reload packet. In This Figure the filter set index (Transaction 0) is labeled as “filt” with the remaining coefficient content labeled “c n ”. When a single filter set has been specified the “filt” transaction is not present. See Coefficient Reload and Coefficient Reload Tab for details on how to generate the reload packet coefficient content.
