PCI_TRDY_N
N24
PCIT5V
I/O
-
Sustained Tri-state. Target Ready indicates that the
bus target is ready to complete the current data
phase.
PCI_STOP_N
P24
PCIT5V
I/O
-
Sustained Tri-state. It indicates that the target is
requesting that the master stop the current
transaction.
PCI_IDSEL
K26
PCIT5V
IN
-
Used as Chip Select during conguration read/write
cycles.
PCI_DEVSEL_N
P26
PCIT5V
I/O
-
Sustained Tri-state. It indicates whether any device
on the bus has been selected.
PCI_REQ_N
F23
PCIT5V
I/O
-
If the PNX1500 is the arbiter of the PCI bus, this pin
acts as a request input for an external device,
otherwise it is driven by the PNX1500 as a PCI bus
master to request the use of the PCI bus.
PCI_GNT_N
D24
PCIT5V
I/O
-
If the PNX1500 is the arbiter of the PCI bus, this pin
acts as an output to grant the requester, otherwise it
Indicates to the PNX1500 that an access to the bus
has been granted.
PCI_REQ_A_N
G23
PCIT5V
IN
-
If the PNX1500 is the arbiter of the PCI bus, this pin
acts as a request input for an external device.
This pin can also be used as an input for an
external interrupt line for the TM3260.
PCI_GNT_A_N
D25
PCIT5V
I/O
-
If the PNX1500 is the arbiter of the PCI bus, this pin
acts as an output to grant the requester. If the
internal PCI arbiter is not used, this pin can be used
as an input for an external interrupt line for the
TM3260.
PCI_REQ_B_N
H23
PCIT5V
IN
-
If the PNX1500 is the arbiter of the PCI bus, this pin
acts as a request input for an external device.
This pin can be used as an input for an external
interrupt line for the TM3260. This pins is also used
as a DSACK signal when using the M68K system
bus on the PCI-XIO interface.
PCI_GNT_B_N
D26
PCIT5V
I/O
-
If the PNX1500 is the arbiter of the PCI bus, this pin
acts as an output to grant the requester. If the
internal PCI arbiter is not used, this pin can be used
as an input for an external interrupt line for the
TM3260.
PCI_PERR_N
P23
PCIT5V
I/O
-
Sustained Tri-state. Parity errors are generated/
received by the PNX1500 through this pin.
PCI_SERR_N
R25
PCIT5V
OD
-
System Error. This signal is asserted when
operating as a target when it detects an address
parity error.
