Interrupt Level Register 4 (bits 16-23)
This register is used to define the level of the VMEbus IRQ5 interrupt and
the VMEbus IRQ6 interrupt. The VMEbus level 5 (IRQ5) interrupt and the
VMEbus level 6 (IRQ6) interrupt may be mapped to any local bus interrupt
level.
the VMEbus IRQ6 interrupt. The VMEbus level 5 (IRQ5) interrupt and the
VMEbus level 6 (IRQ6) interrupt may be mapped to any local bus interrupt
level.
VIRQ5 LEVEL These bits define the level of the VMEbus IRQ5 interrupt.
VIRQ6 LEVEL These bits define the level of the VMEbus IRQ6 interrupt.
Interrupt Level Register 4 (bits 8-15)
This register is used to define the level of the VMEbus IRQ3 interrupt and
the VMEbus IRQ4 interrupt. The VMEbus level 3 (IRQ3) interrupt and the
VMEbus level 4 (IRQ4) interrupt may be mapped to any local bus interrupt
level.
the VMEbus IRQ4 interrupt. The VMEbus level 3 (IRQ3) interrupt and the
VMEbus level 4 (IRQ4) interrupt may be mapped to any local bus interrupt
level.
VIRQ3 LEVEL These bits define the level of the VMEbus IRQ3 interrupt.
VIRQ4 LEVEL These bits define the level of the VMEbus IRQ4 interrupt.
