Hello all.
I'm considering using a 40x2 chip for a project I'm working on. I'm going through the datasheet to have a better understanding of the chp's internals. What is not clear to me at the moment, is how I am supposed to connect the power to the chip. I see it has dual +V, 0V pins (44x2 SMD version) and I can find circuits using the PIC18F45K22 either having both +V/0V pins connected or using just one of the pairs. Is there a reason for selecting one over the other?
