None
Add the 2’s complement number ‘2n’ to
the PC. Since the PC will have incre-
mented to fetch the next instruction, the
new address will be PC + 2 + 2n. This
instruction is a two-cycle instruction.

Bit ‘b’ in register ‘f’ is set.
If ‘a’ is ‘0’, the Access Bank is selected.
If ‘a’ is ‘1’, the BSR is used to select the
GPR bank (default).
If ‘a’ is ‘0’ and the extended instruction
set is enabled, this instruction operates
