The choice is determined by the device address field in the command: 000000for group 0 or 000100 for group 1. The control information is indicated by the value ofbits 14 and 15 of the index register (R), or the accumulator if R=000, and has the followingformat:0 1415Not Used1 1 1 1 1 1 1 1 1 1 1 1 1CX XO 0 0 0-2Forced interruption control is provided by the setting of bit 14. If bit 14 is on, a processinterrupt is forced for the selected group (group 0 or 1). The setting of bit 15 determinesif interruption requests are to be presented for an equal or an unequal comparisonbetween the selected digital input group register and the reference register. When bit 15is set on, an interruption request is presented to the system for an equal comparison.When bit 15 is set off, the interruption request occurs for an unequal comparison.The set-digital-input-interrupt-control command turns on the device-busy bit in thedigital input ISW. The addressed digital input group remains busy to all subsequent commands(except another set-digital-input-interrupt-control with bit 14 on or a read ISWcommand) until an interruption request has been presented by the group.This command applies to digital input groups 0 and 1 only if they have the ProcessInterrupt feature installed. If this feature is not installed, the command does not applyto the Digital Input feature.Set Test Signal0 5 8 11 16 20 26 31Op code R Fun Zeros Mod DA MA00001 XXXO 01000000001 OXXXOOXXXXXXi iI I II II lit!

Selection of the desired digital inputgroup is made by the device address field contents in the command to the addressed multifunctionmodule.The value to be set into the digital input register is determined by the setting of bit 15 inthe index register (R), or the accumulator if R=000. If bit 15=0, the 16-bit digital inputregister is set to all O's. If bit 15=1, the digital input register is set to all l's. A 3-microseconddelay must precede the issuance of a read/reset or read-digital-input-register commandto obtain the test data. A read/reset-digital-input-register command must be issuedto restore the digital input circuits to their original status.IBM 5012 Multifunction Module Model Al 13-19
