1) RW-delay and t
A refer to the next following bus cycle (including an access to an on-chip X-Peripheral).
2) Read data are latched with the same clock edge that triggers the address change and the rising RD edge.
Therefore address changes before the end of RD have no impact on read cycles.
3) These parameters refer to the latched chip select signals (CSxL). The early chip select signals (CSxE) are
specified together with the address and signal BHE (see figures below).
