<pre>
MODIFICATION HISTORY:</pre><pre> Ver Who Date Changes
----- ---- -------- -----------------------------------------------
1.00a ecm 08/16/01 First release
1.00b jhl 02/21/02 Repartitioned the driver for smaller files
1.10b mta 03/21/07 Updated to new coding style
2.00a ktn 10/30/09 Updated to use HAL API's. _m is removed from all the macro
definitions.
2.05a adk 15/05/13 Fixed the CR:693066
Added the IsStartedTmrCtr0/IsStartedTmrCtr1 members to the
<a class="el" href="struct_x_tmr_ctr.html">XTmrCtr</a> instance structure.
The IsStartedTmrCtrX will be assigned XIL_COMPONENT_IS_STARTED in
the XTmrCtr_Start function.
The IsStartedTmrCtrX will be cleared in the XTmrCtr_Stop function.
There will be no Initialization done in the
XTmrCtr_Initialize if both the timers have already started and
the XST_DEVICE_IS_STARTED Status is returned.
Removed the logic in the XTmrCtr_Initialize function
which was checking the Register Value to know whether
a timer has started or not.
