3.5 Biquad Filter Allocation on Playback Channel

Table 3-6 shows the assignment of these biquad filters to a specific channel on the DAC playback path based on the DAC_DSP_BQ_CFG[1:0] register setting of DSP_CFG1 (P0_R115) register. When no additional filtering is needed for the system application, setting DAC_DSP_BQ_CFG[1:0] to 2'b00 disables the Digital Biquad Filters for all channels. Table 3-7 also shows the mapping of the biquad filter coefficients in the TAC5x1x register space.

Table 3-6 Biquad Filter Allocation to the Playback Channel
Programmable Biquad Filter Record Channel Allocation Using P0_R115_D[3:2] Register Setting
DAC_DSP_BQ_CFG[1:0] = 2'b01 (1 Biquad per Channel) DAC_DSP_BQ_CFG[1:0] = 2'b10 (Default) (2 Biquads per Channel) DAC_DSP_BQ_CFG[1:0] = 2'b11 (3 Biquads per Channel)
