Write Cycle Timing
Figure 2 illustrates the Z8500 Write cycle timing. All
register addresses and /INTACK must remain stable
throughout the cycle. If /CE goes active after /WR goes

active, or if /CE goes inactive before /WR goes inactive,
then the effective Write cycle is shortened. Data must be
available to the peripheral prior to the falling edge of /WR.
