SPI DC Electrical Characteristics
This table provides the DC electrical characteristics for the SPI.
21.2
SPI AC Timing Specifications
This table and provide the SPI input and output AC timing specifications.
This figure provides the AC test load for the SPI.
Figure 56. SPI AC Test Load
Figure 57 and Figure 58 represent the AC timing from Table 67. 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.

Note:
1. Output specifications are measured from the 50% level of the rising edge of SPICLK to the 50% level of the signal. Timings
are measured at the pin.
2. 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).
