Notes:
1. Output specifications are measured from the 50 percent level of the rising edge of CLKIN to the 50 percent level of
the signal. Timings are measured at the pin.
2. The symbols 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).
