The VXI/VME IRQ3 line interrupt assertion mode. This uses the standard VXI/VME ROAK (release on acknowledge) interrupt mechanism rather than the older VME RORA (release on register access) mechanism.

The VXI/VME IRQ4 line interrupt assertion mode. This uses the standard VXI/VME ROAK (release on acknowledge) interrupt mechanism rather than the older VME RORA (release on register access) mechanism.

The VXI/VME IRQ5 line interrupt assertion mode. This uses the standard VXI/VME ROAK (release on acknowledge) interrupt mechanism rather than the older VME RORA (release on register access) mechanism.

The VXI/VME IRQ6 line interrupt assertion mode. This uses the standard VXI/VME ROAK (release on acknowledge) interrupt mechanism rather than the older VME RORA (release on register access) mechanism.

The VXI/VME IRQ7 line interrupt assertion mode. This uses the standard VXI/VME ROAK (release on acknowledge) interrupt mechanism rather than the older VME RORA (release on register access) mechanism.
