TMS320F28035 EPwm to trigger CLA task but not CPU ISR

Lucas Sinopoli

Hi there,

I am trying to use the EPwm1 module to trigger Cla Task 1 without triggering any ISR in the CPU.

In other words, when an EPwm interruption happens I want to execute a task in the Cla but no code at all in the Cpu.

Is this possible? Would you be able to provide me with some help on how to do it?

I have no issues at all in triggering the Cla from the EPwm interruption or from the ADC EOC. What I cannot find a way to do is to block the Cpu from servicing the ISR.

Thanks,

Lucas

Hi Lucas,

Any interrupt ISR will not get executed unless that interrupt has been enabled in PIE. Did you try disabling the EPwm interrupt in PIE by wrtting '0' to specific field of Interrupt Enable register (E.g. PieCtrlRegs.PIEIER3.bit.INTx1 = 0 to disable EPWM1_INT).

Vivek Singh
