ARM Compiler toolchain v4.1 for µVision Using the Compiler

Using the Inline and Embedded Assemblers of the ARM Compiler
7.31 Compiler support for embedded assembler
The compiler enables you to include assembly code out-of-line in one or more C or C++
function definitions. Embedded assembler provides unrestricted, low-level access to the target
processor, enables you to use the C and C++ preprocessor directives, and gives easy access to
structure member offsets.
