Is it possible to selectively disable particular ADC SAR interrupts from running my ISR?
Sure, you can do that, just unmask the bit 0 of ADC_SAR_INTR_MASK_REG register is fine.
If I do disable EOS interrupts, how will this impact my ability to undertake measurements of Signal 1? I'm using the command: ADC_1_IsEndConversion(ADC_1_WAIT_FOR_RESULT);
Recommend you use INJ channel to detect signal 1, then this INJ channel have its own EOS bit in ADC_SAR_INTR_MASK_REG register.
Thanks for your reply. After much scratching of my head, and staring at the datasheet for the ADC SAR I was able to sort my issue out. This is what I ended up doing. Note that I am using CH1 for Signal 1 and CH0 for Signal 2. I'm also using the INJ channel for monitoring chip temperature.
1. Turning off ALL ADC related interrupts EXCEPT for the range interrupts on the channel I am using to monitor Signal 2. This means my ISR will only get run for out-of-range events on that channel. I did this using the following code (my component is called "ADC_1")
ADC_1_SAR_INTR_MASK_REG = 0x00; // Turn off all interrupts
ADC_1_IRQ_StartEx(ADC_1_ISR_LOC); // Enable ISR
ADC_1_SAR_RANGE_INTR_MASK_REG = 0x01; // Enable out-of-range interrupts for CH0 only
2. Monitoring the appropriate bit on the ADC_1_SAR_INJ_RESULT_REG (for Temperature) and ADC_1_SAR_INTR_REG (for Signal 1) in a while loop (using the function ADC_1_IsEndConversion() ) whenever I needed to sample those signals. This means that whilst the ADC_1_SAR_INTR_REG is getting updated at the end of every scan cycle (which is happening about once every 10-15usec), I'm only paying attention to it when I need to and its never generating an interrupt.
