MC68CRX Cross-Assembler Users Manual

摘要

This in-house report is a technical user's manual containing all the information needed to utilize a Fortran Cross-Assembler (MC68CRX) for the Motorola MC68000 microprocessor. The Cross-Assembler was developed in-house at RADC (IRAP). A program listing (Fortran 77) is also included, along with information concerning hardware connections from the MC68000 to a DEC mainframe computer. This manual describes the MC68CRX cross-assembler and a Fortran transfer program, which were developed to facilitate programming of the Motorola MC68000 microprocessor, and development of MC68000 based systems. Both programs are written in Fortran 77, which allows the user to utilize the features of a mainframe computer, such as the DEC 11/70 or DEC 11/45. The cross-assembler translates MC68000 assembly language code into machine language. The transfer program downloads the machine code to the MC68000.
