TDM/SI
Figure 31 and Figure 32 represent the AC timing from Table 45. 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 31 shows the SPI timing in slave mode (external clock).
Figure 31. SPI AC Timing in Slave Mode (External Clock) Diagram
Figure 32 shows the SPI timing in master mode (internal clock).
