INTC and IVOR_branch_table

Hello everyone.
I'm working on MPC5777M. I have a problem with INTC management. When the PIT_CVAL reaches zero and sets the interrupt flag (TFLG0.TIF) register at 1, I jump to the IVOR_branc_table correctly(i think). Although the address is right I can not succeed in making the next jump for managing the IVOR4. It almost seems as if I lose control of the device.

I set the INTC_CPR2 to priority 0 and the register INTC_PSR [TFLG0] to 1 as read on some Application Notes, the IVOR_branch_table address is correct so I do not understand where the problem is.

Do you have any suggestions? Any example?
