Interrupt Request: These outputs indicate
programmable interrupt requests generated from any
of a number of card actions. Although there is no
specific mapping requirement for connecting interrupt
lines from the PD6729 to the system, a common use
is to connect these pins to the corresponding signal
name in the system.
Interrupt Request 3 / PCI Bus Interrupt A: This
output indicates a programmable interrupt request
generated from any of a number of card actions.
Although there is no specific mapping requirement for
connecting interrupt lines from the PD6729 to the
system, a common use is to connect this pin to the
system IRQ3 signal or to the PCI bus INTA# signal.
Interrupt Request 4 / PCI Bus Interrupt B: This
output indicates a programmable interrupt request
generated from any of a number of card actions.
Although there is no specific mapping requirement for
connecting interrupt lines from the PD6729 to the
system, a common use is to connect this pin to the
system IRQ4 signal or to the PCI bus INTB# signal.
Interrupt Request 5 / PCI Bus Interrupt C: This
output indicates a programmable interrupt request
generated from any of a number of card actions.
Although there is no specific mapping requirement for
connecting interrupt lines from the PD6729 to the
system, a common use is to connect this pin to the
system IRQ5 signal or to the PCI bus INTC# signal.
Interrupt Request 7 / PCI Bus Interrupt D: This
output indicates a programmable interrupt request
generated from any of a number of card actions.
Although there is no specific mapping requirement for
connecting interrupt lines from the PD6729 to the
system, a common use is to connect this pin to the
system IRQ7 signal or to the PCI bus INTD# signal.
PCI Bus V
a 3.3- or 5-volt power supply. The PCI bus interface
pin outputs listed in this table
the voltage applied to these pins, independent of the
voltage applied to other PD6729 pin groups.
