3.4 Biquad Filter Allocation on Recording Channel

Table 3-6 shows the assignment of these biquad filters to a specific channel on the ADC recording path based on the ADC_DSP_BQ_CFG[1:0] register setting of DSP_CFG0 (P0_R114) register. When no additional filtering is needed for the system application, setting ADC_DSP_BQ_CFG[1:0] to 2'b00 disables the Digital Biquad Filters for all channels. Table 3-6 also shows the mapping of the biquad filter coefficients in the TAC5x1x register space.

Table 3-2 Biquad Filter Allocation to the Record Channel
Programmable Biquad FilterRecord Channel Allocation Using P0_R114_D[3:2] Register Setting
ADC_DSP_BQ_CFG[1:0] = 2'b01 (1 Biquad per Channel) ADC_DSP_BQ_CFG[1:0] = 2'b10 (Default) (2 Biquads per Channel) ADC_DSP_BQ_CFG[1:0] = 2'b11 (3 Biquads per Channel)
