Host interface
Figure 8.
The Host interface consist of the shift clock, the frame synchronization signal, the
ADCchannel data output, and the DAC-channel data input.
Two modes of serial transfer are available :
Both modes are selected by the Hardware Control pins (HC0, HC1).
The data to the device, input/output are MSB-first in 2’s complement format (see
When Control Mode is selected, the device will internally generate an additional Frame
Synchronization Pulse (Secondary Frame Synchronization Pulse) at the midpoint of the
original Frame Period. If the device is in slave mode the additional frame sync (secondary
frame sync pulse) must be generated by the processor. The Original Frame Synchronization
Pulse will also be referred to as the Primary Frame Synchronization Pulse.
