Demultiplexed bus timings (continued)
1. RW-delay and t
2. Read data are latched with the same clock edge that triggers the address change and the rising RD edge.
3. Partially tested, guaranteed by design characterization.
Therefore address changes before the end of RD have no impact on read cycles.
