Description
An invalid operation (such as division by zero) is performed.
Input data (PVN), block memory, operation constant (NMAX, NMIN, HH, H_, L_, LL) or tag data is a subnormal number or NaN (not a
number).
An overflow has occurred.
High limit range error occurrence (HH) < high limit range error return (H_), low limit range error return (L_) < low limit range error
occurrence (LL), or input high limit (NMAX) < input low limit (NMIN)
