SECTION 2
MC68EN302 MODULE BUS CONTROLLER
2.1 INTRODUCTION
The model of the MC68EN302 is such that the internal 302 functions are unaffected by the
addition of an Ethernet controller and the DRAM controller. The 302 core sees that it must
arbitrate with other bus masters for access to the ‘external’ bus. In the MC68EN302, the
Module Bus Controller provides the arbitration between the 302 core and the other modules
(Ethernet and DRAM) for access to the bus external to the MC68EN302. The functions
provided by the Module Bus Controller (MBC) are as follows:
Interfaces between internal 68000 bus and the Module Bus.
Performs Dynamic Bus sizing utilizing the chip select logic of the internal 68302.
Provides Interrupt handling for Module Bus modules.
Performs bus arbitration between external sources, the Module Bus, and the 68302
core.
