Gate A20 Turn-On Sequence Timing

When writing to the command and data port

with hardware speedup, the IOW timing shown

in the figure titled “IOW Timing for Port 92” in

the Timing Diagrams Section is used. This

setup time is only required to be met when using

hardware speedup; the data must be valid a

minimum of 0 nsec from the leading edge of the

write and held throughout the entire write cycle.
