In this example, the bias system is set to 1⁄3. The transfer is terminated by CE returning to logic 1. After the last bit is

transmitted, the state of the SDI/SDAIN line is not important.

Fig 45. SPI-bus example

For a temperature readout (see Section 8.10.4.1 on page 38), the R/W bit must be logic 1.

The next data byte following is provided by the PCA8538 as shown in Figure 46.
