3.6 768 kHz Sample Rate

Only linear phase (DECI_FILT = 00) decimation filter response is supported for 768 kHz sample rate. AGC, DRE, DRC, bi-quads, channel summers, and digital mixer processing blocks are not supported. Only one channel is supported. It can be an analog channel or a digital PDM microphone.
