A51 Macro Assembler

The A51 Assembler is a macro assembler for the 8051 family of microcontrollers. It supports all 8051 derivatives. It translates symbolic assembly language mnemonics into relocatable object code where the utmost speed, small code size, and hardware control are critical. The macro facility speeds development and conserves maintenance time since common sequences need only be developed once. The A51 assembler supports symbolic access to all features of the 8051 architecture.

The A51 assembler translates assembler source files into a relocatable object modules. The DEBUG directive adds full symbolic information to the object module and supports debugging with the µVision Debugger or an in-circuit emulator. In addition to object files, the A51 assembler generates list files which may optionally include symbol table and cross reference information.
