Hi!

Instruction btfsc means:  bit test file, skip if clear. In your case it
says:  test bit 2 of STATUS register and jump over next instruction if it is
zero, else execute next instruction. Zero flag is set, if the result of
previous operation was zero.

example:

        btfsc   STATUS, Z
        goto    SOMEWHERE
        clrf    PORTB

If zero flag Z is clear, program clears PORTB; if it's set, it goes to
SOMEWHERE.
