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.

The contents of register ’f’ are incre-

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’.
