2.2.2 Z80X30 Write Cycle Timing
The write cycle timing for the Z80X30 is shown in
Figure 2-2. The register address on AD7-AD0, as well as
the state of /CS0 and /INTACK, are latched by the rising
edge of /AS. R//W must be Low when /DS falls to indicate
AD7 - AD0

a write cycle. The leading edge of the coincidence of CS1
High and /DS Low latches the write data on AD7-AD0, as
well as the state of R//W.
