● In the case of a direct address and an index modification address, ensure that [S3] is equal
to or larger than [S2].

To be set in the case of out-of-range in indirect access (index modification).
To be set when [S2] is larger than [S3].
To be set when a non-real number is specified for [S1], [S2] or [S3], and the operation unit is
real numbers (SF).
