Inline Assembly

Inline assembly is assembly code that you can insert into your C programs. The Keil C166 C Compiler supports two different methods of inline assembly.

• Traditional Inline Assembly:
  Traditional inline assembly requires that you place your assembly instructions between ASM and ENDASM directives and that you compile your C source file into a .SRC file using the SRC directive which you must assemble with the Keil A166 Assembler.
• Extended Inline Assembly:
  Integrated inline assembly inserts the assembly code directly into the object file output by the compiler and requires no further processing by the assembler. Inline assembly source blocks are marked by the __asm keyword.
