Characteristics
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 [3 ≤ WS ≤ 7] timing is specified for 3 wait states.) Three wait states is the minimum value otherwise.
Timings 100 and 107 are guaranteed by design, not tested.
All timings 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.
Note: Address lines A[0–17] hold their state after a
read or write operation. AA[0–3] do not hold their
state after a read or write operation.
