The MC68EN302 module bus controller provides basic interface capabilities to the module bus as well as basic
system responsibilities. The features of the module bus controller are:
• Interface Between Internal 68000 bus and the Module Bus.
• Provision for Dynamic Bus Sizing, Using the Chip Select Logic of the 68302 Core.
• Handling of Interrupts for the Ethernet Controller and DRAM Controller.
• Coordination of Bus Mastership from External Sources, the Module Bus, and the MC68EN302 Core.
• Provides two CAS lines
• Provides two RAS lines (two banks supported)
• DRAM address multiplexing on standard address bus
• Programmable up to three wait states
• 100 nS DRAM for zero wait states at 20 MHz
• 80 nS DRAM for zero wait states at 25 MHz
• CAS before RAS refresh and refresh support during system reset
