Hi,

ADC doesn’t support the sequential conversion for multiple channels using a single software trigger. Moreover, just a SC1A (or SC1[0]) can be used for software trigger. None of the SC1B-SC1n registers are used for software trigger operation.

You should involve the PDB to trigger multiple channels. You can find several threads discussing PDB. For example
