; Description : This function is the ISR used to notify uC/OS-II that a system tick has occurred.
;
; The following C-like pseudo-code describe the operation being performed in the code below.
;
; Save all registers on the current task's stack:
; Use the PUSH_ALL macro
; Get the SREG, set Bit #7 and save onto the task's stack using -Y addressing
; Use the PUSH_SP macro to save the task's hardware stack pointer onto the current task's stack
; OSIntNesting++;
; if (OSIntNesting == 1) {
; OSTCBCur->OSTCBStkPtr = SP
; }
; Clear the interrupt; Not needed for the timer we used.
; Notify uC/OS-II that a tick has occured
; Notify uC/OS-II about end of ISR
; Restore all registers that were save on the current task's stack:
; Use the POP_SP macro to restore the task's hardware stack pointer
; Use the POP_SREG macro to restore the SREG register
; Use the POP_ALL macro to restore the remaining registers
; Return (DO NOT use a RETI instruction);
