TMS320F280049: CLA task from ADC EOC without end-of- task ISR?

Part Number: TMS320F280049

Hi,

   In the example "cla_ex2_fir32" at the end of task the CPU is interrupt to call the interrupt routine cla1Isr7 () to :

  "Clear the ADC interrupt flag so the next SOC can occur

   Clear the PIEACK bits so another interrupt can be taken"

   Is it possible to do it inside CLA task to avoid a CPU interrupt?

   Ari.

    Hi Ari,

    From the ADC side of things there is actually a "INT1CONT" bit that you can set in the ADCINTSEL1N2 register that will allow each ADC end-of-conversion INT event to propagate without acknowledging the ADCINT flag.
