Description:
The contents of register ’f’ are comple-
mented. If ’d’ is 0 the result is stored in
W. If ’d’ is 1 the result is stored back in
register ’f’.

dfff
ffff
Description:
The contents of register ’f’ are decre-
mented. If ’d’ is 0 the result is placed in the
W register. If ’d’ is 1 the result is placed
back in register ’f’.
If the result is 1, the next instruction, is
executed. If the result is 0, then a NOP is
executed instead making it a 2TCY instruc-
tion.
