118 TA setup before RD or WR deassertion
119 TA hold after RD or WR deassertion
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.
Timing 110, 111, and 112, are not specified for 100 MHz.
In the case of TA negation: timing 118 is relative to the deassertion edge of RD or WR were TA to remain active.
