When set, the coefficients written in the ten coefficient data registers will be loaded into
the filter specified by INDEX
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
