Did anyone notice that at some point Ben switched the addressing between the 65c22 and the LCD from 8- to 4- but mode? I was plugging away at the keyboard interface and realized there were not enough free pins on PortA. Looking at his website the new schematic shows 4-bit and he has an example assembly program using 4-bit. Did he talk about this in one for his videos?
