I am planning to use DSPIC33CK32MP102 for an application that needs time-critical conversion of single ended analog inputs of SAR ADC. For this I am planning to use dedicated core as shown in the image below. For 28-pin UQFN package, ANN0 and ANN1 are not available (see the complete pin functions below). However pins ANA0 and ANA1 are made available!
Does this mean that ANN0 and ANN1 have been internally connected to AVSS? In such case I can use ANA0 and ANA1 instead of AN0 and AN1 to perform single ended ADC conversion. What are the other things that need to be taken care of in this assumption. Please correct me if I am wrong here
Thanks and regards
