Problem 1. You have 3 variables X,Y and Z stored in the following locations X @ 0x30 in bank 0 and Y @ ox31 also in bank 0 and Z at 0xA0 in bank 1. Earlier in the program X and Y have been loaded with data. That part of the program has already been written and debugged. Now, you have to write a segment of code that will switch X and Y. You may use location Z if you need to without having to save Z. Hints: Dont forget BANKSELs where you need them. Remember, you must not destroy the data before you move it. You will need to use MOVF AND MOVWF instructions. Dont forget that you need the 2^nd operand with the MOVF but not with the MOVWF instruction. It might be a good idea to do a block diagram of a flow chart before you write your code.
