A51 ASSEMBLER PDF
A51 – Assembler Kit The A51 Assembler Kit for the microcontroller family enables you to write assembler programs for practically any derivatives. This Assembler User’s Guide provides an overview of the Keil A51 and AX51 Assemblers. It contains the following chapters. Introduction provides a brief. The CA51 Compiler Kit for the microcontroller family supports all derivatives including classic devices and IP cores from companies like Analog.

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. Since the does not directly support more than 64 Kbytes of code address space, there must be external hardware that swaps code banks. Warning messages and error messages are listed at the end of the MAP file. The overlay-map displays the structure of the program and the location of the bit and data segments of each function.
Functions that are frequently invoked from multiple banks should be located in the common area. It contains the following chapters.
Keil A51 Macro Assembler
The common area contains program sections and constants that must be available at all times. The macro facility speeds development and conserves maintenance time since common sequences need only be developed once. Macro Processor discusses how to use assembelr macro expansion capabilities of the assembler. It is an endless.
It also allows you to generate different applications from one assembly source file. This allows exact display of program. List of all our Products. The position of each error is clearly marked. Each input module and the library modules included in the application are listed.
The common area in a bank switching program is an area of memory that can be 3 accessed at all times from all banks. Write a review on this product! By default, the following code sections are automatically located in the common area:.
In addition to object files, the A51 assembler generates list files which may optionally include symbol table and cross reference information.
Error messages and warning messages are included in the listing file.
In addition to object files, the A51 assembler generates list files which optionally may include symbol table and cross reference information. This chapter discusses the directives that are available. These directives are useful when using indirectly called functions or when disabling overlaying for debugging. Listing File Following is an example listing file generated by the assembler. Information about assembler invocation and the object file generated is printed.
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 if the common area is not swapped.
MPL has several predefined macro processor functions that perform many useful operations like string manipulation or number processing. BL51 produces a MAP file extension.
The A51 Assembler translates an assembler source file into a relocatable object module. The common area cannot be physically. Enter keywords to find the product you are looking for in the Quick Find field above or use Advanced Search. The Standard Macro Processor is the easier macro processor to use.

By continuing to use our site, you asssembler to our cookies. The A51 Assembler is a macro assembler for the microcontroller family. It translates symbolic assembly language mnemonics into relocatable object code where the utmost speed, small code size, and hardware control are critical.
Assembling Programs specifies how to run the assembler and generate object files. All the above components also are included as part of the Compiler and Assembler package, as well as the Professional Developer’s Kit package. However, it is easy for you to specify custom settings for your application.
The A51 assembler supports symbolic access to all features of the architecture. By continuing to use our site, you consent to our cookies. It may also contain frequently used code.
