CCS/LAUNCHXL-F28379D: Problem with selecting interrupts

Tool/software: Code Composer Studio

Hello Team TI,

I have INT1 to INT16.

Can we choose any interrupt like below?

// Enable CPU INT3 which is connected to EPWM1-3 INT:
//
    IER |= M_INT3;

//
// Enable EPWM INTn in the PIE: Group 3 interrupt 1-3
//
    PieCtrlRegs.PIEIER3.bit.INTx1 = 1;
    PieCtrlRegs.PIEIER3.bit.INTx2 = 1;
    PieCtrlRegs.PIEIER3.bit.INTx3 = 1;

Can I select lik following,

// Enable CPU INT3 which is connected to EPWM1-3 INT:
//
    IER |= M_INT3;

//
// Enable EPWM INTn in the PIE: Group 3 interrupt 1-3
//
    PieCtrlRegs.PIEIER3.bit.INTx7 = 1;
    PieCtrlRegs.PIEIER3.bit.INTx8 = 1;
    PieCtrlRegs.PIEIER3.bit.INTx9 = 1;
