Note 1
tWST and tWW are valid in EPP 19 only if WAIT is low when WR becomes active else tWST and tWW are measured from WAIT
Note 2
The PC87322VF design guarantees that WRITE will not change from low to high before DSTRB or ASTRB goes from low to high
Note 3
In EPP 19 IOCHRDY is measured from WR or RD
