Specifies the index for each of the seven bands of the filter
coefficient that needs to be written to. Each filter has 5
coefficients that need to be loaded into the 10 coefficient
registers (MSB,LSB) before setting the index and WR bit.
Steps to write coefficients:
1. Write the five 20-bit coefficient values to
DAP_COEF_WR_XX_MSB and DAP_COEF_WR_XX_LSB
registers (XX= B0,B1,B2,A1,A2)
2. Set INDEX of the coefficient from the table below.
3. Set the WR bit to load the coefficient.
NOTE: Steps 2 and 3 can be performed with a single write to
DAP_FILTER_COEF_ACCESS register.
Coefficient address:
Band 0 = 0x00
Band 1 = 0x01
Band 2 = 0x02
Band 3 = 0x03
Band 4 = 0x04
...
Band 7 = 0x06
