TMS320F280025C: Problem to acknowledge CPU timer interrupt

Part Number: TMS320F280025C

Hi experts,

I have an issue, I configure in my code three timers. TIMER0 and TIMER2 => interrupt and TIMER1 classic mode only to count.

For this I use TIMER0, TIMER1 and TIMER2, TIMER0 is connected to the ePIE module it work fine (I use this to transmit TX CAN frames) and I want to use TIMER2 for regulation interrupt. 

It doesn't work for TIMER2. 

I never get out of this interrupt : so how acknowledge this interrupt ? I can't use "Interrupt_clearACKGroup(x)" because TIMER2 isn't part of PIE mapping no ?

You can see my code :

/**Initialization timer for ISR TX_CAN*/
timer_cpu_init(CPUTIMER0_BASE);
/**Timer for CAN communication Interrupt all of (us) 10ms*/
timer_cpu_config(CPUTIMER0_BASE, DEVICE_SYSCLK_FREQ, 10000);
Interrupt_register(INT_TIMER0, &isr_timer);
CPUTimer_enableInterrupt(CPUTIMER0_BASE);
Interrupt_enable(INT_TIMER0);

/**Initialization timer for STEP_START_TIMER precharge and monitoring utilization*/
timer_cpu_init(CPUTIMER1_BASE);
/**Timer for STEP_START_TIMER precharge all of (us) PARAM_T_PL_US and monitoring utilization*/
config_cpu_timer(CPUTIMER1_BASE);

/**Initialization timer for regulation interrupt*/
timer_cpu_init(CPUTIMER2_BASE);
/**Timer for regulation interrupt all of (us) 25us*/
timer_cpu_config(CPUTIMER2_BASE, DEVICE_SYSCLK_FREQ, 25);
Interrupt_register(INT_TIMER2, &isr_regulation);
CPUTimer_enableInterrupt(CPUTIMER2_BASE);
Interrupt_enable(INT_TIMER2);

/**Start timer for interrupt CAN (to send frames)*/
CPUTimer_startTimer(CPUTIMER0_BASE);
/**Start timer for precharge step (to measure precharge voltage when timer is reached)*/
CPUTimer_startTimer(CPUTIMER1_BASE);
/**Start timer for regulation interrupt*/
CPUTimer_startTimer(CPUTIMER2_BASE);

Thanks,

Damien
