Figure 68. Setting up SPI_STREAMCN
The next step shows how to perform the Controlled Streaming mode so that the master device will read
ADC_DOUT from ADDR 0x1A, 0x1B, 0x1C, then wrap back to ADDR 0x1A, and repeat this process for four
times. After this process, deassert CSB to end the Controlled Streaming mode.
