Description
PCI Clock. 33 or 66 MHz.
PCI Address/Data. AD[31:0] is a physical address during the first
clock of a PCI transaction; it is the data during subsequent clocks.
When the Geode CS5535 companion device is a PCI master, AD[31:0]
are outputs during the address and write data phases, and are inputs
during the read data phase of a transaction.
When the Geode CS5535 companion device is a PCI slave, AD[31:0]
are inputs during the address and write data phases, and are outputs
during the read data phase of a transaction.
PCI Bus Command and Byte Enables. During the address phase of
a PCI transaction, when FRAME# is active, C/BE[3:0]# define the bus
command. During the data phase of a transaction, C/BE[3:0]# are the
data byte enables.
C/BE[3:0]# are outputs when the Geode CS5535 companion device is
a PCI master and inputs when it is a PCI slave.
PCI Parity. PAR is the parity signal driven to maintain even parity
across AD[31:0] and C/BE[3:0]#.
The Geode CS5535 companion device drives PAR one clock after the
address phase and one clock after each completed data phase of write
transactions as a PCI master. It also drives PAR one clock after each
completed data phase of read transactions as a PCI slave.
PCI Cycle Frame. FRAME# is asserted to indicate the start and dura-
tion of a transaction. It is de-asserted on the final data phase.
FRAME# is an input when the Geode CS5535 companion device is a
PCI slave.
Normally connected to a 10k to15k Ω external pull-up. This signal is in
TRI-STATE mode after reset.
PCI Device Select. DEVSEL# is asserted by a PCI slave, to indicate to
a PCI master and subtractive decoder that it is the target of the current
transaction.
As an input, DEVSEL# indicates a PCI slave has responded to the cur-
rent address.
As an output, DEVSEL# is asserted one cycle after the assertion of
FRAME# and remains asserted to the end of a transaction as the
result of a positive decode. DEVSEL# is asserted four cycles after the
assertion of FRAME# if DEVSEL# has not been asserted by another
PCI device when the Geode CS5535 companion device is pro-
grammed to be the subtractive decode agent.
Normally connected to a 10k to15k Ω external pull-up. This signal is in
TRI-STATE mode after reset.
