AD[31:0]
I/O
PCI Address and Data.
The standard PCI address and data lines. The
address is driven with PCI Frame assertion and data is driven or received in
the following clocks.
B25, B24, G22,
F24
CBE_[3:0]
I/O
Bus Command and Byte Enables.
During the address phase, C/BE_n[3:0]
define the Bus Command. During the data phase, C/BE[3:0]_n define the Byte
Enables.
PCI Frame
.
This pin
is driven by a PCI master to indicate the beginning and
duration of a PCI transaction.
PCI Initiator Ready.
This pin is asserted low by the master to indicate that it
is able to transfer the current data transfer. A data was transferred if both
IRDY_n and TRDY_n are asserted low during the rising edge of the PCI
clock.
PCI Target Ready
.
This pin is asserted low by the target to indicate that it is
able to receive the current data transfer. A data was transferred if both
IRDY_n and TRDY_n are asserted low during the rising edge of the PCI
clock.
Device Select.
This pin is driven by the devices which have decoded the
addresses belonging to them.
PCI Stop.
This pin is asserted low by the target to indicate that it is unable to
receive the current data transfer.
PCI Parity
.
This pin is driven to even parity by PCI master over the AD[31:0]
and C/BE_n[3:0] bus during address and write data phases. It should be
pulled high through a weak external pull-up resistor. The target drives parity
during data read.
PCI INTA_.
PCI interrupt input A. It connects to PCI INTA_n when normal
modes of PCI Interrupts are supported.
PCI INTB_.
PCI interrupt input B. It connects to PCI INTB_n when normal
modes of PCI Interrupts are supported.
PCI INTC_.
PCI interrupt input C. It connects to PCI INTC_n when normal
modes of PCI Interrupts are supported.
PCI INTD_.
PCI interrupt input D. It connects to PCI INTD_n when normal
modes of PCI Interrupts are supported.
