67.6.3.1 FLEXCOM SPI Characteristics

In Figure 67-11 and Figure 67-12, the MOSI line shifting edge is represented with a 0 hold time. However, it is important to note that for this device, the MISO line is sampled prior to the MOSI line shifting edge. As shown in Figure 67-10, the device sampling point extends the propagation delay (t_p) for device and routing delays to more than half the SPI clock period, whereas the common sampling point allows only less than half the SPI clock period.

As an example, an SPI device working in mode 0 can be safely driven if the SPI host is configured in mode 0.
