No.
All timings for 100 MHz are measured from 0.5 · Vcc to .05 · Vcc
WS is the number of wait states specified in the BCR.
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
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
