APPENDIX A
Programming a Single AD73311 for Data Mode Operation
This section describes a typical sequence in programming a
single codec to operate in normal DATA mode. It details the
control (program) words that are sent to the device to configure
its internal registers and shows the typical output data received
during both program and data modes. The device is connected
in Frame Sync Loop-Back Mode (see Figure 13), which forces
an input word from the DSP’s Tx Reg each time the codec
outputs a word via the SDO/SDOFS lines. In Step 1, the part
has just been reset and on the first output event the codec pre-
sents an invalid output word

. The DSP’s Tx Reg contains a

control word that programs CRB with the data word 0x03. In
Step 2, the control word from the DSP’s Tx Reg has been sent
to the codec’s SPORT and the output word has been received
by the DSP’s Rx Reg. In Steps 3 and 4, register CRC is pro-
grammed with 0x01, which powers up the analog section. In
Steps 5 and 6, the codec is put into programming mode by
setting the
PGM
/DATA bit of CRA. In Step 7, the output word
from the device is now a valid ADC word as the device has been
programmed into data mode. Note also that the codec now
expects DAC data to be sent to it and will interpret any data
from the DSP to be 16-bit DAC data.
NOTE
1
Data output by the codec in program mode is invalid and should not be inter-
preted as ADC data. The only exception to this is output caused by register
reads or CEE being enabled on control word writes.
