(PC) + 2 + 2n → PC
None
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.

None
Bit ‘b’ in register ‘f’ is set. If ‘a’ is ‘0’,
the Access Bank will be selected,
overriding the BSR value. If ‘a’ = 1,
then the bank will be selected as
per the BSR value.
