As long as each set of SOCs has identical trigger select and ACQPS settings, multiple trigger sources can be used while still achieving synchronous operation.
The following example demonstrates synchronous operation between ADCA and ADCB while using three SOCs and two trigger sources. Figure 15-15 demonstrates that any combination of relative trigger timings still results in synchronous operation.
Note that any trigger source that can be selected in the TRIGSEL field can be used except for software triggering. There is no way to issue the software triggers for all ADCs simultaneously, so this results in asynchronous operation. ADCINT1 or ADCINT2 can also be used as a trigger when the ADCINTSOCSEL1 and ADCINTSOCSEL2 registers are configured identically for all ADCs and software triggering is not used to start the chain of conversions.
