SPI AC Timing Specifications

This figure provides the AC test load for the SPI.

Figure 41. SPI AC Test Load

These figures represent the AC timing from Table 56. 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.

This figure shows the SPI timing in slave mode (external clock).

This figure shows the SPI timing in Master mode (internal clock).

Notes:

1. 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.

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, tNIKHOV symbolizes the NMSI

outputs internal timing (NI) for the time tSPI memory clock reference (K) goes from the high state (H) until outputs (O) are

valid (V).
