+; -----------------------
+;
+; 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
+; restoring a task context has to be written in an asm file.
+;
+; 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.

+Changes between V1.2.4 and V1.2.5
+
+ + Introduced portGLOBAL_INTERRUPT_FLAG definition to test the global
+ interrupt flag setting. Using the two bits defined within
+ portINITAL_INTERRUPT_STATE was causing the w register to get clobbered
+ before the test was performed.
+
+Changes from V1.2.5
+
+ + Set the interrupt vector address to 0x08. Previously it was at the
+ incorrect address for compatibility mode of 0x18.
+
+Changes from V2.1.1
+
+ + PCLATU and PCLATH are now saved as part of the context. This allows
+ function pointers to be used within tasks. Thanks to Javier Espeche
+ for the enhancement.
+
+Changes from V2.3.1
+
+ + TABLAT is now saved as part of the task context.
+
+Changes from V3.2.0
