The contents of register ’f’ are com-
plemented. If ’d’ is 0, the result is
stored in WREG. 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 WREG by performing an
unsigned subtraction.
If 'f' = WREG
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, over-
riding the BSR value. If ‘a’ = 1, then
the bank will be selected as per the
BSR value (default).
