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’ = 1, then the bank will be
selected as per the BSR value
(default).

None
Compares the contents of data
memory location ‘f’ to the contents
of W by performing an unsigned
subtraction.
If ‘f’ = W
instruction is discarded and a NOP
is executed instead, making this a
two-cycle instruction. 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 (default).
