Figure 15-3. Memory Read and Write Cycles
Notice that the data times are different, depending on whether data are being read or writ-
ten. T
for data read specifies how long the data must remain valid following the rising
hold
edge of T1 when the clock cycle repeats. T
for data write specifies how long the data
DHZV
remain valid once /WEx goes high, and must be at least one-half of a CPU clock cycle.
