SPI AC Timing Specifications
This table provides the SPI input and output AC timing specifications.
This figure provides the AC test load for the SPI.
Figure 48. SPI AC Test Load
These figures represent the AC timing from Table 70. 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.

Notes:
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, tNIKHOV 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. The maximum SPICLK input frequency is 66.666 MHz.
