PrefaceThis reference manual is a source of information primarily for programming the applicationsof System/7 in machine language. The manual describes the operation and useof the machine instructions and the functions that are used to program the processorand I/O devices. Specific topics covered are:• Processor functional characteristics• Priority interruptions• Instruction set• I/O commands and device status• Operator console• Interval timers• Asynchronous Communications Control Attachment• Binary Synchronous Communications Adapter• 1130 host attachment• Operator station• Analog input and output• Digital input and output• 2790 Control• Disk storage module• 5024 I/O Attachment EnclosureThe reference appendixes include summaries of instructions, I/O commands, and statuswords; a character code chart; and examples of how to convert a voltage value to or frombinary data.The reader must have a background in sensor-based data processing concepts and befamiliar with the hexadecimal numbering system as used in IBM systems. The manual NumberSystems, GC20-1618, contain information on hexadecimal numbering.Prerequisite reading for this publication is IBM System/ 7 System Summary, GA34-0002.Information on customer interfaces to the I/O modules (analog, digital, and 2790 Control)appears in IBM System17 Installation Manual—Physical Planning, GA34-0004.This manual has been organized so that each chapter forms a module within the entire manual.Each chapter has its own front cover, table of contents, and page and figure numbers. A mastertable of contents appears at the beginning of the manual, and a master index is included at theend of the manual.The modular presentation gives the user an option of using this manual in its published format,or of using the chapters in combination with information from other sources. That is, it may bedesirable to insert one or more chapters from this manual into another publication.The name of the manual appears at the foot of each left-hand page; the title of the chapterappears at the foot of each right-hand page. The user who separates the chapters shouldfind this arrangement helpful for retrieving and reorganizing them.Examples of data and instruction formats used throughout the manual give the binarybit settings and their equivalent hexadecimal values. Bit positions that can be set by theprogram or programmer are denoted by an X. Bit positions that are not used by a particulardata or instruction format are denoted by *. The latter bit positions, however,must be set to 0 values.Preface vii
