Description:
Never branches. LBRN is effectively a 4-byte NOP that requires three
cycles to execute. LBRN is included in the instruction set to provide a
complement to the LBRA instruction. The instruction is useful during
program debug, to negate the effect of another branch instruction without
disturbing the offset byte. A complement for LBRA is also useful in compiler
implementations.
Execution time is longer when a conditional branch is taken than when it is
not, because the instruction queue must be refilled before execution
resumes at the new address. Since the LBRN branch condition is never
satisfied, the branch is never taken, and the queue does not need to be
refilled, so execution time is always the smaller value.
