TM4C129EKCPDT: TI-RTOS TIMER PRIORITY SETUP

Hi, I am working on TM4C129EKCPDT and TI-RTOS Timer.

Both timer is working.  I want to setup timer priority. 

Timer_Handle  timer1, timer2 ; 

Timer_Params timer1_ISR_params;
Timer_Params_init(&timer1_ISR_params);
timer1_ISR_params.period = 10;                   //interval 10us

Timer_Params timer2_ISR_params;
Timer_Params_init(&timer2_ISR_params);
timer2_ISR_params.period = 1;                    //interval 1us

timer1 = Timer_create(Timer_ANY, timer1_ISR, &timer1_ISR_params, &eb_task); // timer create for cap bank charging
if(timer1 == NULL)
{
System_abort("*** timer1 Create FAIL***");
}
Timer_stop(timer1 );

timer2 = Timer_create(Timer_ANY, timer2_ISR, &timer2_ISR_params, &eb_task); // timer create for cap bank charging
if(timer2 == NULL)
{
System_abort("*** timer2 Create FAIL***");
}
Timer_stop(timer2);
