to the upper bound (effective address operand). The upper bound is a twos
complement integer. If the register value is less than zero or greater than the upper
bound, a CHK instruction exception (vector number 6) occurs.
X — Not affected.
N — Set if Dn < 0; cleared if Dn > effective address operand; undefined otherwise.
