SFIE
SYSFAIL* Interrupt Enable
Writing a 1 to this bit enables the SFINT
interrupt condition in the VMEbus Interrupt
Status Register (VISTR) to assert the VMEbus
IRQ[7:1] selected by LINT[3:1]. This bit is
cleared by a hard reset and is not affected by a
soft reset.

AFIE
ACFAIL* Interrupt Enable
Writing a 1 to this bit enables the AFINT
interrupt condition in the VMEbus Interrupt
Status Register (VISTR) to assert the VMEbus
IRQ[7:1] selected by LINT[3:1]. This bit is
cleared by a hard reset and is not affected by a
soft reset.

DIRQ[7:1]
Drive VMEbus Interrupt Request [7:1]
Writing a 1 to one of these bits causes the
VME-MXI-2 to assert the corresponding
VMEbus interrupt request. When the interrupt
driven from these bits is acknowledged, the
value in the VMEbus Status ID Register
(VSIDR) is returned and the DIRQ[7:1] bit
clears, releasing the interrupt. These bits are
cleared by a hard reset and are not affected by a
soft reset. The state of the VMEbus interrupt
request lines can be monitored in the VMEbus
Interrupt Status Register (VISTR).
