This file contains a design example using the timer counter driver (XTmCtr) and hardware device using fast interrupt mode.This example assumes that the interrupt controller is also present as a part of the system.
MODIFICATION HISTORY:
Ver Who Date Changes
1.00a bss 07/31/12 First release 4.2 ms 01/23/17 Added 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. 4.5 mus 07/05/18 Updated example to call TmrCtrDisableIntr function with correct arguments. Presently device id is being passed instead of interrupt id. It fixes CR#1006251. 4.5 mus 07/05/18 Fixed checkpatch errors and warnings.

This function does a minimal test on the timer counter device and driver as a design example.
The purpose of this function is to illustrate how to use the XTmrCtr component. It initializes a timer counter and then sets it up in compare mode with auto reload such that a periodic interrupt is generated.
This function uses interrupt driven mode of the timer counter.
IntcInstancePtr | is a pointer to the Interrupt Controller driver Instance |
TmrCtrInstancePtr | is a pointer to the XTmrCtr driver Instance |
DeviceId | is the XPAR_<TmrCtr_instance>_DEVICE_ID value from xparameters.h |
IntrId | is XPAR_<INTC_instance>_<TmrCtr_instance>_VEC_ID value from xparameters.h |
TmrCtrNumber | is the number of the timer to which this handler is associated with. |
