TMS320F28377D: Synchronous Operation with Uneven SOC Numbers and different triggers on 28337D

Part Number:TMS320F28377D

Hello,

I would like to sample different analog values simultaneously and having two different trigger sources: PWM1_SOCA_TRIGGER (TBCTR = 0) and PWM1_SOCB_TRIGGER (TBCTR = PERIOD).

For instance, in ADC A I have 4 channels to convert and in ADC B only two channels. I need that first 2channels of both ADC modules are sampled simultaneously. Is there any problem in SOC priority if SOC conversions (in time) are not in order? (See module A in time line, the order is SOC0, SOC1, SOC4,SOC5...). 

Is there any difference in time conversion with the following setup due to priority?

Thank  you very much!
