During V
This parameter is sampled, but not 100% tested.
For test conditions, see AC Test Conditions, Figures A and B.
These parameters are specified with C
This parameter is guaranteed, but not tested.
WE is high for read cycle.
CE and OE are low for read cycle.
Address is valid prior to or coincident with CE transition low.
All read cycle timings are referenced from the last valid address to the first transitioning address.
