(PC) + 2 + 2n → PC
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.

0 ≤ f ≤ 255
0 ≤ b ≤ 7
a ∈ [0,1]
1 → f<b>
None
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
in Indexed Literal Offset Addressing
mode whenever f ≤ 95 (5Fh). See
Section 23.2.3 “Byte-Oriented and
Bit-Oriented Instructions in Indexed
Literal Offset Mode” for details.
