A coefficient value is 13 bits wide and takes a single half word. Thus, one VPI Control write carries one phase’s worth of coefficients. The last half-word in a quad-word is not used for 7tap coefficients.
The Vertical Polyphase scaler coefficients have only five or three values per phase, so the last three (or five) entries are unused. The Vertical Polyphase coefficient packing is shown in Figure 10-30 and Figure 10-31.
