The editor and debugger are integrated into a single application and provide a seamless embedded project development environment.

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 optionally may include symbol table and cross reference information.

The A51 Assembler supports two different macro processors:. Conditional assembly of sections of code can help you achieve the most compact code possible.
