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.
