WS is the number of wait states specified in the BCR. An expression is used to compute the number listed as the minimum or
maximum value, as appropriate.
Timings 100, 107 are guaranteed by design, not tested.
All timings for 100 MHz are measured from 0.5 × Vcc to 0.5 × Vcc.
Timing 118 is relative to the deassertion edge of RD or WR even if TA remains asserted.
