Note 2: For a MOVX read operation, on the falling edge of ALE, Port 0 is held by a weak latch until overdriven by external memory. Note 3: All parameters apply to both commercial and industrial temperature operation, unless otherwise noted. Note 4: CST is the stretch cycle value as determined by the MD2, MD1, and MD0 bits of the CKCON register. tCLCL , tCLCH , tCHCL are time periods associated with the internal system clock and are related to the external clock. See the System Clock Time Periods table. Note 5: All signals characterized with load capacitance of 80pF except Port 0, Port 2, ALE, PSEN, RD, and WR with 100pF. The following signals, when configured for memory interface, are also characterized with 100pF loading: Port 4 ( CE0-3, A16–A19), Port 5.4–5.7 ( PCE0-3), Port 6.0–6.5 (CE4-7, A20, A21), Port 7 (demultiplexed mode A0–A7). Note 6: References to the XTAL, XTAL1 or CLK signal in the timing diagrams are to assist in determining the relative occurrence of events, not for determining absolute signal timing with respect to the external clock. |
