Bits 00 to 07 correspond tocommunications ports 0 to 7.If the simple backup operation is used to perform a write or compareoperation for a Memory Card, a communications port will beautomatically allocated, and the corresponding flag will be turnedON during the operation and turned OFF when the operation hasbeen completed.Turns ON when an error occurred during execution of a networkinstruction. Turns OFF at normal completion. Bits 00 to 07 correspondto communications ports 0 to 7.If the simple backup operation is used to perform a write or compareoperation for a Memory Card, a communications port will beautomatically allocated. The corresponding flag will be turned ON ifan error occurs and will be turned OFF if the simple backup operationends normally.These words contain the completion codes for the correspondingport numbers when network instructions have been executed. Thecontents will be cleared to 0000 hex when background executionhas been completed. Words A203 to A210 correspond to communicationsports 0 to 7.If the simple backup operation is used to perform a write or compareoperation for a Memory Card, a communications port will beautomatically allocated, and a completion code will be stored in thecorresponding word.A395.10 Turns ON when an instruction execution error or illegal access erroroccurs in an instruction being executed in the background. TurnsOFF when power is turned ON or operation is started.A595 and A596These words receive the output when the output of an instructionexecuted in the background is specified for an index register. Nooutput will be made to IR00.Range: 0000 0000 to FFFF FFFF hexLower 4 digits: A595, Upper 4 digits: A596A597This word receives the output when the output of an instruction executedin the background is specified for a data register. No outputwill be made to DR00.Range: 0000 to FFFF hexA598.01 This flag is turned ON when matching data is found for aSRCH(181) executed in the background.10-14 CJ2 CPU Unit Software User’s Manual
