 Flag operation
Name Description
Set in case of out-of-range values in indirect access (index modification).
Latest error
(SR7) Set when the comparison range is outside the accessible range.
Hold error Set when the control data is outside the range.
(SR8)
Set when the block length is outside the settable range.
Set when the comparison blocks of S2 and S3 match.
= flag
(SB)
Reset when the comparison blocks of S2 and S3 do not match.
