WS is the number of wait states specified in the BCR. The value is given for the minimum for a given category. (For example,
for a category of [2 ≤ WS ≤ 7] timing is specified for 2 wait states.) Two wait states is the minimum otherwise.
Timings 100 and107 are guaranteed by design, not tested.
All timings for 150 MHz are measured from 0.5 × V
The WS number applies to the access in which the deassertion of WR occurs and assumes the next access uses a minimal
number of wait states.
Timing 118 is relative to the deassertion edge of RD or WR even if TA remains asserted.
