I want to design 3 phase grid tied inverter. I have seen this (TIDA - 01606) reference design.
1.65V is connected in 17th pin. 17th pin going to ADCINA3.
I had a look in the firmware (F28739D). In that I can't able to find the ADCINA3 result registers.
I think ADCINA3 is not used in the firmware. Please clear my doubt 1.65V is needed or not.
If needed for purpose it is used Please clear.
