The contents of register ’f’ are com-
plemented. 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, overriding the BSR value.
If ’a’ is 1, the Bank will be selected
as per the BSR value.

None
Compares the contents of data
memory location 'f' to the contents
of W by performing an unsigned
subtraction.
If 'f' = WREG
instruction is discarded and an NOP
is executed instead making this a
two-cycle instruction. If ’a’ is 0, the
Access Bank will be selected, over-
riding the BSR value. If ’a’ is 1, the
Bank will be selected as per the
BSR value.
