NOTES:
26. Decimating Halfband Filter #4 Coefficients are shown for reference only. If it is desired to implement this FIR filter, these coefficients would have
to be loaded into the FIR Coefficient RAM (They are not included in the ROMd Fir Filter Coefficient memory).
27. The 22-bit ROMd FIR filter coefficients are located in the upper 22 bits of the Read register when read back from ROM memory (except for
Halfband #4). These bits occupy the upper six bytes (24 bits) with the two LSBs of the lower byte (bits 9:8 of 31:0) being zero. The decimal value
for the hexadecimal coefficient is calculated by first converting the hexadecimal value to decimal and the dividing by 2
23
(8388608).
