16.3.4.4.3 FIR5 Parameter Packet. The FIR5 parameter packet is composed of seven
16-bit half-words and described in the table below.
16.3.4.4.4 Application Example. The FIR5 function is used in the fractionally spaced
equalizer. The following example demonstrates how the function descriptor structure can be
used to implement a fractionally spaced equalizer.
