Hello Hongmei, As we talked about earlier, it's really up to you to figure out what suits your application best, and all interrupts can be useful for you. Let’s go through an example of how to pick the right interrupt. If you need to measure 3 currents and 1 voltage, you’ll usually want to capture all 3 currents at the same time for control purposes. So, it makes sense to use the same Start of Conversion (SoC) from different ADCs, and then assign a different SoC for the voltage measurement. For instance: I1 -> ADC A - SoC 0 I2 -> ADC C - SoC 0 I3 -> ADC B - SoC 0 V1 -> ADC A - SoC 1 Since we’re looking for the end of conversion, you can select one of the interrupts from ADC A with EoC1 as the interrupt source for the SoC.
