3-7-12 DOUBLE AREA RANGE COMPARE: ZCPL(116)
Purpose Compares a 32-bit unsigned binary value (CD+1, CD) with the range defined
by lower limit (LL+1, LL) and upper limit (UL+1, UL). The results are output to
the Arithmetic Flags.
This instruction is supported by CS1-H, CJ1-H, CJ1M, and CS1D CPU Units
only.
