The OS bit in the DSD mode is used to select the operating rate of the analog FIR. The OS bits must be set before
setting the DSD bit to1.
TDMCA Format
The PCM1792 supports the time-division-multiplexed command and audio (TDMCA) data format to simplify the host
control serial interface. The TDMCA format is designed not only for the McBSP of TI DSPs but also for any
programmable devices. The TDMCA format can transfer not only audio data but also command data, so that it can
be used together with any kind of device that supports the TDMCA format. The TDMCA frame consists of command
field, extended command field, and some audio data fields. Those audio data are transported to IN devices (such
as a DAC) and/or from OUT devices (such as an ADC). The PCM1792 is an IN device. LRCK and BCK are used
with both IN and OUT devices so that the sample frequency of all devices in a system must be the same. The TDMCA
mode supports a maximum of 30 device IDs. The maximum number of audio channels depends on the BCK
frequency.
