Causes program execution to continue at location PC + displacement. The displacement, calculated by the
assembler and linker, is a two’s complement integer that represents the relative distance from the current
PC to the destination label. The assembler determines if the PC relative displacement is a short branch
(
<label [–2
10
≤ displacement < 2
10 , W]) or a long branch (
>label [–2
20
≤ displacement < –2
10 , W and 2 10

< 2
