It provides for transmitting and receiving the signal, decoding a set of assigned order codes, performing the specified operation, and responding to the signaling CPU. If a CPU has the CPU-signaling-and-recsponse facility installed, it can address the SIGNAL PROCESSOR instruction to itself. All orders are executed as defined. code order ---- ------------ 00 Invalid and Unassigned 01 Sense 02 External Call 03 Emergency Signal 04 Start 05 Stop 06 Restart 07 Initial Program Reset 08 Program Reset 09 Stop and Store Status 0A Initial Microprogram Load 0B Initial CPU Reset 0C CPU Reset 00-FF Invalid and Unassigned ............ 360/65 functional characteristics multiprocessor pg32-34 http://bitsavers.informatik.uni-stuttgart.de/pdf/ibm/360/funcChar/A22-6884-3_360-65_funcChar.pdf multiprocessor write direct modified for: System Reset, External Start, Log I/O Interruprs, System call .... -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
