Notes
1.
Timings are measured from 1.5 V of the clock to 1.5 V of the signal.
2.
Capacitive load for all maximum output timings is 50 pF. Minimum output timings are for a theoretical no
load condition - untested.
3.
Data Output timing applies to all signal pins whether tristate I/O or output only.
4.
Setup and Hold parameters apply to all signal pins whether tristate I/O or input only.
5.
Only mode 14:13 = 00 is tested and guaranteed.
