%R97F.2 DEFCARTE General I/O card error bit (**)
%R97F.1 DEFCONF General I/O card configuration error bit (**)
%R97F.0 DEFBUS General serial I/O bus link error bit (**)
Variables
(*) This counter is incremented by the system whenever an overrun is detected. It is reset
by the user programme.
(**) These bits ate set by the system whenever an error is detected.
