SPI
Figure 35 provides the AC test load for the SPI.
Figure 35. SPI AC Test Load
Figure 36 through Figure 37 represent the AC timings from Table 50. Note that although the specifications
generally reference the rising edge of the clock, these AC timing diagrams also apply when the falling edge
is the active edge.
Figure 36 shows the SPI timings in slave mode (external clock).

Figure 37 shows the SPI timings in master mode (internal clock).
