(f) – WREG),
skip if (f) < (WREG)
(unsigned comparison)
None
Compares the contents of data memory
location ’f’ to the contents of WREG by
performing an unsigned subtraction.
If the contents of ’f’ are less than the
contents of WREG, then the fetched
instruction is discarded and a NOP is
executed instead, making this a
two-cycle instruction.

DAW adjusts the eight-bit value in
WREG, resulting from the earlier addi-
tion of two variables (each in packed
BCD format) and produces a correct
packed BCD result.
