The following figure provides the AC test load for the SPI.
Figure 64. SPI AC Test Load
Figure 65 and Figure 66 represent the AC timing from Table 74. 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.
The following figure shows the SPI timing in slave mode (external clock).

Note:
1 The symbols used for timing specifications follow the pattern of t
(first two letters of functional block)(signal)(state) (reference)(state) for
inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tNIKHOX symbolizes the internal
timing (NI) for the time SPICLK clock reference (K) goes to the high state (H) until outputs (O) are invalid (X).
2. Output specifications are measured from the 50% level of the rising edge of CLKIN to the 50% level of the signal. Timings are
measured at the pin.
