3.3 96 kHz Sample Rate

All three decimation filter options are supported for 96 kHz operation. 96 kHz mode supports AGC and DRE, but not for all channel combinations. Figure 3-2 shows the channel combinations supported when AGC or DRE is enabled. Figure 3-3 shows the channel combinations support when AGC or DRE is disabled.
