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 PCM1792A 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 PCM1792A 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.
