The next data byte following is provided by the PCA8530 as shown in Figure 41. 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 40. SPI-bus example Fig 41. SPI-bus protocol - read example Data transfers are terminated by de-asserting CE (set CE to logic 1). Fig 42. SPI-bus protocol - write example |
