if Overflow bit is ‘ 0 ’,
(PC) + 2 + 2n  PC
None
If the Overflow bit is ‘ 0 ’, then the
program will branch.
The 2’s complement number ‘2n’ is
added to the PC. Since the PC will have
incremented to fetch the next
instruction, the new address will be
PC + 2 + 2n. This instruction is then a
two-cycle instruction.
