PCI-to-PC Card (PCMCIA) Controller — PD6729
Datasheet

IRQ[12:9]
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.

IRQ3/INTA#
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_VCC
PCI Bus VCC: These pins can be connected to either
a 3.3- or 5-volt power supply. The PCI bus interface
pin outputs listed in this table (Table 1) will operate at
the voltage applied to these pins, independent of the
voltage applied to other PD6729 pin groups.
