8-9
8.6 OE, WEL, WEH TIMING
These are new signals added to the MC68EN302 that do not exist on the MC68302.
8.6.1 OE Timing
During a read, the timing on the OE signal is similar to the MC68302 UDS, LDS lines
(assertion and deassertion reference the same clock edges as UDS, LDS). Reference
Figure 6-2 (Read Cycle Timing Diagram) in the MC68302 User’s Manual. The following
MC68302 specifications define OE timing:
MC68302 Spec 9 - CLK0 High to OE Asserted
MC68302 Spec 12 - CLK0 Low to OE Negated
8.6.2 WEL, WEH Timing
During a write, the timing on the WEL, WEH signals is similar to the MC68302 UDS, LDS
lines (assertion and deassertion reference the same clock edges as UDS, LDS). Reference
Figure 6-3 (Write Cycle Timing Diagram) in the MC68302 User’s Manual. The following
MC68302 specifications define WEL, WEH timing:
MC68302 Spec 9 - CLK0 High to WEL, WEH Asserted
MC68302 Spec 12 - CLK0 Low to WEL, WEH Negated
