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,
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).
