APPENDIX A
INTERFACING AN MC68EC020 TO A DMA DEVICE
THAT SUPPORTS A THREE-WIRE BUS ARBITRATION
PROTOCOL
The MC68EC020 supports a two-wire bus arbitration protocol; however, it may become
necessary to interface the MC68EC020 to a device that supports a three-wire arbitration
protocol. Figure A-1 shows a method by which this can be achieved.
