This example demonstrates the ARM thumb interworking.
The Compiler is forced into ARM mode by unchecking "use thumb mode" 
in the compiler tab of theoptions for target menu.

#pragma ARM and #pragme THUMB directives are used to selectivley switch 
between the instruction sets. 

The compiler/linker will also automatically optimise the arm/thumb interworking 
across the project for best performance/codesize
