R/W delay and t A refer to the next bus cycle. 2. Read data is latched with the same clock edge that triggers the address change and the rising RD edge. Therefore address changes which occur before the end of RD have no impact on read cycles. Table 176. Demultiplexed bus (continued) Symbol Parameter FCPU = 40 MHz TCL = 12.5 ns Variable CPU clock 1/2 TCL = 1 to 64 MHz Unit Min Max Min Max Obsolete Product(s) - Obsolete Product(s) |
