Functions that are frequently invoked from multiple banks should be located in the common area. The macro facility speeds development and conserves maintenance time since common sequences need only be developed once. By continuing to use our site, you consent to our cookies. Each input module and the library modules included in the application are listed. Conditional assembly of sections of code can help you achieve the most compact code possible. It translates symbolic assembler language mnemonics into executable machine code.

Conditional assembly of sections of code can help you achieve the most compact assember possible. The memory map 3 contains the usage of the physical memory.

Between A51 and ASM51

It allows you to define and use macros in your assembly programs. The Standard Macro Processor is the easier macro processor to use. The standard macro syntax is compatible with that used in many other assemblers. The bank switching process requires approximately 50 CPU cycles and consumes an additional 2 bytes of stack space.

MACRO Assembler Directive

The macro facility speeds development and conserves maintenance time since common sequences need only be developed once. The A51 Assembler translates an assembler source file into a relocatable object module.


Products Download Events Support Videos. It generates a listing file optionally with symbol table and cross reference. This greatly reduces the overall memory requirement of most applications. Information about assembler invocation and the object file generated is printed.

A MACRO Assembler Directive

The linker automatically selects the appropriate run-time library and links only those library modules that are required. The listing contains a source line number and the object code generated by each wssembler line. The A51 assembler translates a51 macro assembler source files into a relocatable object modules.

This site uses cookies to store information on your computer. This allows exact display of program. The A51 Assembler is a macro assembler for the microcontroller family.

A51 Macro Assembler

The code in the common area is either duplicated in each bank if the entire program area is swapped or can be located in a separate area or EPROM assejbler the common area is not swapped. Maxro overlay-map displays the structure of the program and the location of the bit and data segments of each function. A51 macro assembler Started and Creating Applications By carefully grouping functions in the different banks, you can create very large, efficient applications.

BL51 displays the invocation line and the memory model. It is an endless.

When your C program calls a function located in a different bank, it switches the bank, jumps to the desired function, restores the previous bank when the function completesand returns execution to the calling routine. It may also contain frequently used code.


The A51 Assembler generates complete line number, symbol, and type. By a51 macro assembler, the following code sections are automatically located in the common area:. The register banks used, and the total number of warnings and errors are at the end of the listing file. The hardware that does this must be controlled by software running on the However, it is easy for you to specify custom settings for your application.

The position of each error is clearly marked. It translates symbolic assembly language mnemonics into relocatable object code where the utmost speed, small code size, and hardware control are critical.

The A51 assembler supports symbolic access to all features of the architecture. Listing File Following is an example a51 macro assembler file generated by the assembler. It also allows you to generate different applications from one assembly source file.
