The contents of W are ANDed with
register ‘f’. If ‘d’ is ‘0’, the result is stored
in W. If ‘d’ is ‘1’, the result is stored back
in register ‘f’ (default). If ‘a’ is ‘0’, the
Access Bank will be selected. If ‘a’ is ‘1’,
the BSR will not be overridden (default).

None
If the Carry bit is ‘1’, 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 instruc-
tion, the new address will be
PC + 2 + 2n. This instruction is then a
two-cycle instruction.
