My question is about bank selection using the STATUS RPO/RP1 bits vs. the BANKSEL command. When I need to transition between banks, I simply change the RP0/RP1 bits accordingly before and after the transition. However, I see many examples of code in the archives that use the BANKSEL command. I do not see this command in the spec sheet, well for the 16C773 & 16C715 I use anyway. Is it applicable to all PICs or just certain ones? What are the advantages of its use over the RP0/RP1 select method? Thanks.
