67.16.3 Timing Extraction

In the first two figures below, “SPI Host Modes 1 and 2” and “SPI Host Modes 0 and 3”, the MOSI line shifting edge is represented with a hold time = 0. 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 “MISO Capture in Host Mode”, the device sampling point extends the propagation delay (tp) for client 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 Client working in Mode 0 is safely driven if the SPI Host is configured in Mode 0.
