Characteristics
WS is the number of wait states specified in the BCR.
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 active.
Timings 110, 111, and 112, are not helpful and are not specified for 100 MHz.

Note: Address lines A[0–23] hold their state after a
read or write operation. AA[0–3] do not hold their
state after a read or write operation.
