Digital Power.
Digital Ground.
CardBusN (Active-Low). Selects mode of operation for PCI output
buffers. Connect this pin to ground for CardBus operation; connect to
V
Not Usable. No external connections to this pin are allowed.
Cable Not Active. CNA output is provided for use in legacy power
management systems. CNA is asserted high when none of the PHY
ports is receiving an incoming bias voltage. This circuit remains
active during the powerdown mode. The CNA pin is TTL-compatible.
This pin can source and sink up to a 6 mA load.
NAND Tree Test Output. When the chip is placed into the NAND
tree test mode, the pin is the output of the NAND tree logic. This pin
is not used during normal operation.
Test. Used by Agere for device manufacturing testing. Tie to V
normal operation.
ROM Clock.
ROM Address/Data.
Test. Used by Agere for device manufacturing testing. Tie to V
normal operation.
Digital Power.
Digital Ground.
CLKRUNN (Active-Low). Optional signal for PCI mobile computing
environment. If not used, CLKRUNN pin needs to be pulled down to
V
PCI Interrupt (Active-Low).
PCI Reset (Active-Low).
PCI Grant Signal (Active-Low).
PCI Request Signal (Active-Low).
PCI Power Management Event (Active-Low)/CardBus Status
Changed (Active-High). When the CARDBUSN signal is high (i.e.,
when the FW323 is communicating directly with the PCI bus and not
the CardBus), a PCI power management event will be indicated if this
signal is low. When the CARDBUSN signal is low (indicating the
FW323 is in CardBus mode), this pin signals that the CardBus status
has changed when it is active-high. (See PC Card Standard, v. 8.0,
Volume 2, Section 5.2.11 for more information regarding CSTSCHG.)
