See I get mindfu*ked.
Because I watched Ben Heck's video on PIC's. And he did like a memetic, think of 1 as "I" in input, and 0 as "O" in Output.
but then he went on and said, "It's the other way around for AVR"
and I'm just left going "Well...now I've recalled that, but which way is it for MSP?"
btw yes I just got done looking it up
