I program only 16CXX processors at work, but I am wondering about the 17C42. For some reason we have 4 or 5 17C42/JWs and I wanted to teach myself the 17C language... Just for the hell of it. My question is... You use this to select bank 1 on an 84. On a 17C42 I will have to use the MOVLB command... like this... What is is the value for bank0 or 1 or 2 or 3????
