Function
BCMP2(502) compares the source data (S) to the ranges defined by pairs of lower and upper limit
values in the comparison block. If S is within any of these ranges (inclusive of the upper and lower
limits), the corresponding bits in the result words (R to R+15 max.) are turned ON. The rest of the bits in
R will be turned OFF.
The number of ranges is determined by the value N set in the lower byte of B. N can be between 0 and
255. The upper byte of B must be 00 hex.
 Number of Ranges
The number of ranges in the comparison block is set in the first word of the block. Up to 256 ranges can
be set.
 Setting Ranges
The values A and B for each range will determine how the comparison operates depending on which
value is larger, as shown below.
· If Value A ≤ Value B
Then, Value A ≤ Comparison range ≤ Value B
