AppendicesInstruction Mnemonic Code Symbol/Operand Function LocationFAILUREPOINTDETECTIONExecutionconditionFPD 269 Output RequiredFPD(269) Diagnoses a failure in an instruction block by monitoring thetime between execution of FPD(269) and execution of aC diagnostic output and finding which input is preventing anoutput from being turned ON.TTime monitoring function:RStarts timing when execution condition A goesON. Generates a non-fatal error if output Bisn't turned ON within the monitoring time.C: Control wordT: Monitoring timeR: 1st registerwordExecutioncondition ANext instruction blockLogic diagnosis block*Logic diagnosisexecution condition CTRError-processingblock (optional)Logic diagnosis functionDetermines which input in Cprevents output B from going ON.Diagnostic output BA-1 Instruction Functions AppA-1-29Other InstructionsInstruction Mnemonic Code Symbol/Operand Function LocationSET CARRYCLEARCARRYSELECT EMBANKSTC@STCCLC@CLCEMBC@EMBCExecutioncondition040 Sets the Carry Flag (CY).
