Function
code
Compares a 16-bit unsigned binary value (CD)
with the range defined by lower limit LL and upper
088
limit UL. The results are output to the Arithmetic
Flags.
Compares a 32-bit unsigned binary value (CD+1,
CD) with the range defined by lower limit (LL+1,
116
LL) and upper limit (UL+1, UL). The results are
output to the Arithmetic Flags.
