18.2 Jump in the Block If RLO = 1 (Unconditional Jump)
The Unconditional Jump instruction corresponds to a “go to label”
instruction. No additional LAD element may be positioned between the left
power rail and the operation. None of the instructions between the jump
operation and the label is executed.
You can use this instruction in all logic blocks: organization blocks (OBs),
function blocks (FBs), and functions (FCs).
