The contents of register 'f' are decre-
mented. If 'd' is 0 the result is placed in the
W register. If 'd' is 1 the result is placed
back in register 'f'.
If the result is 1, the next instruction, is
executed. If the result is 0, then a NOP is
executed instead making it a 2T
tion.

GOTO is an unconditional branch. The
eleven bit immediate value is loaded
into PC bits <10:0>. The upper bits of
PC are loaded from PCLATH<4:3>.
GOTO is a two cycle instruction.
