8.5.1.1 Streaming Mode Operation

Since updating the sixteen channels data registers requires a large amount of data to be passed to the device, the device supports streaming mode. In streaming mode the DAC data registers can be written to the device without providing an instruction command for each data register. Streaming mode is enabled by setting the STR-EN bit. Once enabled the streaming operation is implemented by holding the CS active and continuing to shift new data into the device.

The instruction cycle includes the starting address. The device starts writing to this address and automatically increments the address as long as CS is asserted. If the last DAC data register address has been reached and CS is still asserted, the data for this address is overwritten with the new data.
