ePWM Event Trigger SOC A/B ?

Hi There

(F28027PT piccolo ControlSTICK)

I am getting confused with the A/B designations used for the names of SOCs/ ADC channels and ePWM Triggers.

I have set SOC0 to ADC A1, SOC1 to ADC B1 and SOC2 to ADC B2.

They are all set to be triggered by ADCTRIG9 (ePWM3, ADCSOCA)

However I wish the trigger to be taken from ePWM3B, is the 'B' here linked to the 'B' of the above ADCTRIG ADCSOC ?

Should I be using ADCSOCB for ePWM3B? or for ADC B1 and ADC B2 and ADCSOCA for ADC A1?

Thanks

Hi Toby,

The SOC-A/B are unrelated to PWM channels A/B. You can use any trigger for each of the SOCs. The A/B suffixes are only used to differentiate the two SOCs.

Many thanks Daniel

So SOC A/B are unrelated to PWM A/B and both are unrelated to ADC A/Bx
