None
Subroutine call with a jump up to 1K
from the current location. First,
return address (PC + 2) is pushed
onto the stack. Then, add the 2’s
complement number ‘2n’ 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 a two-cycle instruction.
