/* 
Two interrupt examples are provided - 

 + Method 1 does everything in C code.
 + Method 2 uses an assembly file wrapper.

Code size:
Method 1 uses assembly macros to save and restore the task context, whereas 
method 2 uses functions. This means method 1 will be faster, but method 2 will 
use less code space. 

Simplicity:
Method 1 is very simplistic, whereas method 2 is more elaborate. This 
elaboration results in the code space saving, but also requires a slightly more 
complex procedure to define interrupt service routines. 

Interrupt efficiency:
Method 1 uses the compiler generated function prologue and epilogue code to save 
and restore the necessary registers within an interrupt service routine (other 
than the RTOS tick ISR). Should a context switch be required from within the ISR 
the entire processor context is saved. This can result in some registers being saved 
twice - once by the compiler generated code, and then again by the FreeRTOS code.
Method 2 saves and restores all the processor registers within each interrupt service 
routine, whether or not a context switch actually occurs. This means no registers 
ever get saved twice, but imposes an overhead on the occasions that no context switch 
occurs.
