+Two interrupt examples are provided - \r
+\r
+ + Method 1 does everything in C code.\r
+ + Method 2 uses an assembly file wrapper.\r
+\r
+Code size:\r
+Method 1 uses assembly macros to save and restore the task context, whereas \r
+method 2 uses functions. This means method 1 will be faster, but method 2 will \r
+use less code space. \r
+\r
+Simplicity:\r
+Method 1 is very simplistic, whereas method 2 is more elaborate. This \r
+elaboration results in the code space saving, but also requires a slightly more \r
+complex procedure to define interrupt service routines. \r
+\r
+Interrupt efficiency:\r
+Method 1 uses the compiler generated function prologue and epilogue code to save \r
+and restore the necessary registers within an interrupt service routine (other \r
+than the RTOS tick ISR). Should a context switch be required from within the ISR \r
+the entire processor context is saved. This can result in some registers being saved \r
+twice - once by the compiler generated code, and then again by the FreeRTOS code.\r
+Method 2 saves and restores all the processor registers within each interrupt service \r
+routine, whether or not a context switch actually occurs. This means no registers \r
+ever get saved twice, but imposes an overhead on the occasions that no context switch \r
+occurs. \r
