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).
