 3.00 pkp    01/12/15 First release
 3.01 pkp         01/30/16 Modified SetupTimer to remove XTtcps_Stop before TTC
                                           configuration as it is added in xttcps.c in
                                           XTtcPs_CfgInitialize
 3.01 pkp         03/04/16 Added status check after SetupTicker is called by
                                           TmrInterruptExample
 3.2  mus    10/28/16 Updated TmrCntrSetup as per prototype of
                      XTtcPs_CalcIntervalFromFreq
      ms     01/23/17 Modified xil_printf statement in main function to
                      ensure that "Successfully ran" and "Failed" strings
                      are available in all examples. This is a fix for
                      CR-965028.
 3.10 aru    05/30/19 Updated the example to use XTtcPs_InterruptHandler().
 3.16 adk    04/19/22 Replace infinite while loop with
                       Xil_WaitForEventSet() API.
      adk    20/04/22 Update the Xil_WaitForEventSet() API arguments as
                       per latest API.
 3.18 gm     07/25/23 Invoke XTtcPs_Release to release ttc node.

int TmrInterruptExample	(	XTtcPs *	TtcPsInst,
		u16	DeviceID,
		u16	TtcTickIntrID,
		XScuGic *	InterruptController
	)

This is the main function of the interrupt example.

Parameters

TtcPsInst	is a pointer to the ttc instance.
DeviceID	is the unique ID for the device.
TtcTickIntrID	is the unique interrupt ID for the timer.
InterruptController	is a pointer to the interrupt controller instance..

Returns

XST_SUCCESS to indicate success, else XST_FAILURE to indicate a Failure.
