Figure 58 through Figure 59 represent the AC timing from Table 72. 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 58 shows the SPI timing in Slave mode (external clock).

Figure 59 shows the SPI timing in Master mode (internal clock).
