    Hello Julia,

    Sorry for the delayed response, as I was out of office last week. CLA tasks can be triggered directly by ADC EOC by configuring CLA1TASKSRCSELx.TASKx to an ADC interrupt signal.

    You do not have to execute an ISR to service the ADC interrupt. You can disable this interrupt in the PIE (this does not affect the CLA task trigger). However, it is important that either the CLA task clears ADC interrupt flag (by writing to ADCINTFLGCLR/ADCINTOVFCLR), or the ADC is configured for continuous interrupts. If neither is done, the ADC will not issue a new interrupt signal until the current one has been cleared.

    Best regards,
    Ibukun
