168 / 226 page ![]() 8.12.5.1.2 SPI Slave Mode Timings Section 8.12.5.1.2.1 lists the SPI slave mode timing requirements. Section 8.12.5.1.2.2 lists the SPI slave mode switching characteristics. Figure 8-74 shows the SPI slave mode external timing where the clock phase = 0. Figure 8-75 shows the SPI slave mode external timing where the clock phase = 1. 8.12.5.1.2.1 SPI Slave Mode Timing Requirements NO.
