Hi Friends, When selecting 0100 for the bottom nibble of ADCON1 on the 16F876A, you get 3 A/D channels active. The chart on page 128 of DS39582B shows the three channels to be RA0, RA1, and RA3. I remember some flurry a while back about the data sheet for the 16F876 being wrong in this regard, and that in three channel mode, the three channels are RA0, RA1, RA2. Yet I look at two versions each of the two datasheets and all the tables are the same. I suppose it's possible that three years have elapsed and Microchip has consistently given us incorrect data. Has anyone used this configuration and can confirm if the third channel is in fact RA3 on the 16F876A as it says in the datasheet, or is it RA2 as was bandied about a few years ago her on the list?
