Keil Ax51 Assembler

Conditional Assembly Controls
Set assigns numeric values to variables that are used in $IF and $ELSEIF directives to control conditional assembly sections. The variable names must conform to the standard symbol conventions and are administered separately so that they cannot interfere with other assembly symbols.

clears previous Set assignments that are entered in the options dialog of a higher Target or Group level.
Macro Preprocessor
Enables various Assembler Macro Processors.
  • Standard Assembler Macros are similar to many other macro assemblers. They allow you to define macros that look like standard assembler instructions.
  • MPL Macros are compatible with the Intel ASM-51 Assembler. They allow you to retranslate existing source files that were initially written for this macro assembler.
Special Function Registers
Pre-defines the classic 8051 SFR names.
Include Paths
Allows you to supply one or more paths to search when processing an $INCLUDE file directive.
Misc Controls
Specify any assembler directive for which there is no individual dialog control.
Assembler Control String
Displays the current directives at the assembler command line.
