C166: How Do I Use Inline Assembly

Information in this article applies to:

• C166 All Versions

QUESTION

I can't figure out how to use inline assembly code in my C166 programs. How does it work?

ANSWER

In essence, you must use #pragma asm and #pragma endasm around your assembly code. For example:

void my_func (void)
{

#pragma asm
   NOP
#pragma endasm

}

Then, compile your file using the SRC directive. For example:

c166 mycode.c SRC

The compiler generates a .SRC file which you must assemble with the A166 Macro Assembler.

Note: C166 Version 5 or higher provides an extended in-line assembler that does not longer require the SRC mode of the Compiler.
