Figure 56. TDMCA Frame Example of 6-Ch DAC and 2-Ch ADC With Command Read
Command Field
The normal command field is defined as follows. When the DID bit (MSB) is 1, this frame is used only for device
ID determination, and all remaining bits in the field are ignored.

Bit 31: Device ID enable flag
The DSD1792 operates to get its own device ID for TDMCA initialization if this bit is HIGH.
Bit 30: Extended command enable flag
EMD packet is transferred if this bit is HIGH, otherwise skipped. Once this bit is HIGH, this frame does not
contain any audio data. This is for system initialization.
Bit 29: Daisy chain selection flag
HIGH designates OUT-chain devices, LOW designates IN-chain devices. The DSD1792 is an IN device, so
the DCS bit must be set to LOW.
Bits[28:24]: Device ID. It is 5 bits length, and it can be defined.
These bits identify the order of a device in the IN or OUT daisy chain. The top of the daisy chain defines device
ID 1 and successive devices are numbered 2, 3, 4, etc. All devices for which the DCI is fixed HIGH are also
defined as ID 1. The maximum device ID is 30 each in the IN and OUT chains. If a device ID of 0x1F is used,
all devices are selected as broadcast when in the write mode. If a device ID of 0x00 is used, no device is
selected.
Bit 23: Command Read/Write flag
If this bit is HIGH, the command is a read operation.
Bits[22:16]: Register ID
It is 7 bits in length.
Bits[15:8]: Command data
It is 8 bits in length. Any valid data can be chosen for each register.
Bits[7:0]: Not used
These bits are never transported when a read operation is performed.
Extended command field
The extended command field is the same as the command field, except that it does not have a DID flag.
