CLA access MIER register

Can access the Configuration Registers "MIER" at the CLA?

Example:

                  MMOV32     MR1, #0x00000001

                  MMOVZ16  MR3, @_Cla1Regs.MIER.all

                  MOR32       MR3, MR3, MR1

                  MNOP

                  MNOP

                  MMOV16      @_Cla1Regs.MIER.all, MR3

    Eric,

    The CLA can not access its own registers.

  • Hi Lori,

       Thank you!

        So, it can only access at the c2000 CPU. such as at the CLA1_INTx ISR also. 

        I have other one experience what can not into CLA1_INTx ISR when CLA Task completes.

        My code CLA1_INT1 source is from epwm1. I testified that the CLA Task1 had come in. But can not in to the breakpointer of the INT11.1 when the Task1 completes.

       My Initialize :

       EALLOW;
       PieVectTable.CLA1_INT2 = &cla1_isr1;
       EDIS;

       EALLOW;
       PieCtrlRegs.PIEIER11.bit.INTx1 = 1;
       EPwm1Regs.CMPA.half.CMPA = 62;    
       EPwm1Regs.ETSEL.bit.INTSEL = ET_CTR_ZERO; 
       EPwm1Regs.ETSEL.bit.INTEN = 1;    
       EPwm1Regs.ETPS.bit.INTPRD = ET_1ST;   
       EPwm1Regs.ETCLR.bit.INT = 1;
      
       Cla1Regs.MPISRCSEL1.bit.PERINT1SEL = CLA_INT1_EPWM1INT;  
      
       IER |= M_INT11;           
       EINT;               
       ERTM;             
       EDIS; 
      
      
       interrupt void cla1_isr1()
       { 
     
          PieCtrlRegs.PIEACK.all = PIEACK_GROUP11;  /* set breakpointer here*/
       }
