A251 Macro Assembler

The A251 assembler is a macro assembler for the 251 and 930 microcontroller families. 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 A251 assembler supports symbolic access to all features of the 251 architecture including the Atmel Wireless & Micro devices and the Intel USB devices.

The A251 assembler translates an assembler source file into a relocatable object module. The object file contains full symbolic information for debugging with the µVision Debugger or an in-circuit emulator. In addition to the object file, the A251 assembler generates a list file which may optionally include symbol table and cross reference information.
