thumb.txt

掏美元培训得来的某外国公司推广keil ARM 和LPC2100的源码。

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
