/* This is an application defined callback function used to clear whichever
interrupt was installed by the the vApplicationSetupTimerInterrupt() callback
function - in this case the interrupt generated by the AXI timer. It is
provided as an application callback because the kernel will run on lots of
different MicroBlaze and FPGA configurations - not all of which will have the
same timer peripherals defined or available. This example uses the AXI Timer 0.
If that is available on your hardware platform then this example callback
implementation should not require modification provided the example definition
of vApplicationSetupTimerInterrupt() is also not modified. */
