Hi All, When we say that it is a PIC of 12,16,17 or 18 series, is it that we actually mean to differentiate it with the memory bit it can address at a time. Example PIC 18 series can fetch and process 16bit instruction at a time, similarly PIC 12 series executes 12 bit. In this case how many bits a PIC instruction would be(8,12 or 16)bits? Is it possible that an application developed for PIC 12 could execute on PIC 16 series. And what exactly we mean when we say PIC can address 16 bit at a time? Is the memory addressed in RAM or ROM are they talking about?
