GOTO

Unconditional Branch

Syntax:

[ label ] GOTO k

Operands:

0 ≤ k ≤ 2047

Operation:

k → PC<10:0>

PCLATH<4:3> → PC<12:11>

Status Affected: None

Encoding:

10 1kkk kkkk kkkk

Description:

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'.
