+;
+; For simplicity the RTOS tick interrupt routine uses the __task keyword.
+; As the IAR compiler does not permit a function to be declared using both
+; __task and __interrupt, the use of __task necessitates that the interrupt
+; vector table be setup manually.
+;
+; To write an ISR, implement the ISR function using the __interrupt keyword
+; but do not install the interrupt using the "#pragma vector=ABC" method.
+; Instead manually place the name of the ISR in the vector table using an
+; ORG and jmp instruction as demonstrated below.
+; You will also have to add an EXTERN statement at the top of the file.

+; Saving and Restoring a Task Context and Task Switching
+; ------------------------------------------------------

+; The IAR compiler does not fully support inline assembler, so saving and

+;
+; vPortYield() and vPortYieldFromTick() are usually written in C.  Doing
+; so in this case would required calls to be made to portSAVE_CONTEXT() and
+; portRESTORE_CONTEXT().  This is dis-advantageous as the context switch
+; function would require two extra jump and return instructions over the
+; WinAVR equivalent.
+;
+; To avoid this I have opted to implement both vPortYield() and
+; vPortYieldFromTick() in this assembly file.  For convenience
+; portSAVE_CONTEXT and portRESTORE_CONTEXT are implemented as macros.
