NOTE:
13. The 22-bit ROMd FIR filter coefficients are located in the upper 22 bits of the Read register when read back from ROM memory. 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 2²³ (8388608).
