17.5.2 Controlled Streaming Example
This example shows how to read the 16-bit conversion data (ADC_DOUT) four times using the Controlled Streaming mode. The
ADC_DOUT registers consist of ADC_DOUTH at ADDR 0x1A and ADC_DOUTL at ADDR 0x1B.
The first step
(Figure
35) sets up the SPI_STREAMCN register. This step enters the Controlled Streaming mode by setting
STRM_TYPE high in ADDR 0x03. Since two registers (ADDR 0x1A - 0x1B) need to be read, the STRM_RANGE is 1.

FIGURE 35. 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 and 0x1B, then wrap back to ADDR 0x1A, and repeat this process for four times. After this process, deassert CSB to end
the Controlled Streaming mode.
