No.
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, 107 are guaranteed by design, not tested.
In the case of TA negation: timing 118 is relative to the deassertion edge of RD or WR were TA to remain active.
Address and AA valid to input data valid
RD assertion to input data valid
RD deassertion to data not valid (data hold time)
Address valid to WR deassertion
Data valid to WR deassertion (data setup time)
Data hold time from WR deassertion
WR assertion to data active
WR deassertion to data high impedance
Previous RD deassertion to data active (write)
RD deassertion time
WR deassertion time
Address valid to RD assertion
RD assertion pulse width
RD deassertion to address not valid
TA setup before RD or WR deassertion
TA hold after RD or WR deassertion
