Setting the Interrupt Request Level

NOTE

Interrupts are enabled at power-up, after a SYSRESET, or after resetting the module via the Control Register (see Appendix B). If interrupts are enabled, the system generates an interrupt after writing to any relay control register. The interrupt is generated approximately 13 msec after writing to the register to indicate the end of relay closure/settling time.

As shown in Figure 1-5, the Interrupt Request Level switch selects the priority level that will be asserted. The Interrupt Request Level switch is set in position 1 as shipped from the factory. For most applications this priority level should not be changed. The interrupts are disabled when set to position 'X'. To change the setting, set the switch to the level required.

Interrupts can also be disabled using the Control Register (see Appendix B). Also, consult your mainframe manual to make sure backplane jumpers/switches are configured correctly.
