Comparison Instructions Section 3-7
Flags
Precautions An error will not occur if the lower limit is greater than the upper limit, but 0
(not within the range) will be output to the corresponding bit of R.
Example When CIO 000000 is ON in the following example, BCMP(068) compares the
content of D00100 with the 16 ranges defined in D00200 through D00231 and
turns ON the corresponding bits in D00300 when S is within the range or OFF
when S is not within the range.
3-7-10 EXPANDED BLOCK COMPARE: BCMP2(502)
Purpose Compares the source data to up to 256 ranges (defined by 256 lower limits
and 256 upper limits) and turns ON the corresponding bit in the result word
when the source data is within a range. BCMP2(502) is supported only by the
CS1-H, CJ1-H, and CS1D CPU Unit Ver. 2.0 or later, and CJ1M CPU Unit
(Pre-Ver. 2.0 or Unit Ver. 2.0 or later).
