What is the use of Movf instruction?
The MOVF instruction is widely used to bring data from I/O ports such as Port B into the CPU. We also use the MOVF instruction to bring data into WREG from any special function registers from any location in the Generam Purpose RAM in order to perform arithmetic and operations on them.
What is BCF Assembly?
BCF is a resetting command instruction used for performing reset operations for a specified bit or specified register (simply called bit clearing flag or bit clearing command). Normally BCF resets the specified bit in f registers content.
What is TRIS register?
The TRIS A register controls the direction of the PORT pins even when they are being used as analog inputs. The user must ensure the bits in the TRISA register are maintained set when using them as analog inputs.

How does BNE work?
BNE (short for “Branch if Not Equal”) is the mnemonic for a machine language instruction which branches, or “jumps”, to the address specified if, and only if the zero flag is clear.

Why don’t people use’movfw’instead of movwf?
I deliberately avoid using ‘movfw’ because it’s just too easy to mistype it. (It’s also a tough bug to find since it looks so much like ‘movwf’.) While I’m writing code, I periodically do a ‘Find in Files’ search for ‘movfw’.
