Plug-In Assembly Configuration 40'1@Since a bit in the interrupt byte is set, an interrupt is sent to the 3497A mainframeand sets bit 1 in the 3497A status register. However, unless the SRQ mask (interruptmask for Serial Data) is set for digital interrupt with an SEZ (SElO2) command,an interrupt is not sent to the controller.Thus, for an input to interrupt the controller, a two-level hierarchy of commands isrequired: (1 set the Option 050 assembly mask with a DE slot#,n command and(2) set the 3497A SRQ or interrupt mask with an SE2 or SE102 command.You can monitor the status of the interrupt byte at any time (whether or not an interruptoccurs) by sending the Dl slot# command. The value returned to the controlleris the octal value of the true bits in the interrupt byte.SET WITHSE2 (SE1021COMMANDMASKINTERRUPTTRANSITIONSFigure 91.
