I'm learning to program a PIC18 using assembly language and am curious why there seems to be some redundancy with many instructions. Take the MOVF instruction, for example: MOVLB 0x2 ;select bank 2 MOVF 0x240, W ;move the value at 0x240 to W If my understanding is correct, then the "2" digit in the MOVF instruction is ignored completely, making it redundant since the bank is selected above. From what I've read, it seems that the assembler automatically sets the access "a" bit based on the address when translating to machine code, so what I'm wondering is why the assembler doesn't automatically generate bank select instructions as well? Thanks!
