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 the following figure, the
filter set index (Transaction 0) is labeled as “filt” with the remaining coefficient
content labeled “cn”. 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.
