2-PORT PCI-TO-PCI BRIDGE
Description
Primary FRAME (Active LOW). Driven by the
initiator of a transaction to indicate the beginning and
duration of an access. The de-assertion of P_FRAME_L
indicates the final data phase requested by the initiator.
Before being tri-stated, it is driven to a de-asserted state
for one cycle.
Primary IRDY (Active LOW). Driven by the initiator
of a transaction to indicate its ability to complete current
data phase on the primary side. Once asserted in a data
phase, it is not de-asserted until the end of the data
phase. Before tri-stated, it is driven to a de-asserted
state for one cycle.
Primary TRDY (Active LOW). Driven by the target
of a transaction to indicate its ability to complete current
data phase on the primary side. Once asserted in a data
phase, it is not de-asserted until the end of the data
phase. Before tri-stated, it is driven to a de-asserted state
for one cycle.
Primary Device Select (Active LOW). Asserted by the
target indicating that the device is accepting the
transaction. As a master, PI7C8150A waits for the
assertion of this signal within 5 cycles of P_FRAME_L
assertion; otherwise, terminate with master abort. Before
tri-stated, it is driven to a de-asserted state for one cycle.
Primary STOP (Active LOW). Asserted by the target
indicating that the target is requesting the initiator to
stop the current transaction. Before tri-stated, it is driven
to a de-asserted state for one cycle.
Primary LOCK (Active LOW). Asserted by the
master for multiple transactions to complete.
Primary ID Select. Used as a chip select line for Type
0 configuration access to PI7C8150A configuration
space.
Primary Parity Error (Active LOW). Asserted when
a data parity error is detected for data received on the
primary interface. Before being tri-stated, it is driven to
a de-asserted state for one cycle.
Primary System Error (Active LOW). Can be driven
LOW by any device to indicate a system error condition.
PI7C8150A drives this pin on:
This signal requires an external pull-up resistor for
proper operation.
Primary Request (Active LOW): This is asserted by
PI7C8150A to indicate that it wants to start a transaction
on the primary bus. PI7C8150A de-asserts this pin for
at least 2 PCI clock cycles before asserting it again.
Primary Grant (Active LOW): When asserted,
PI7C8150A can access the primary bus. During idle and
P_GNT_L asserted, PI7C8150A will drive P_AD,
P_CBE, and P_PAR to valid logic levels.
Primary RESET (Active LOW): When P_RESET_L is
active, all PCI signals should be asynchronously tri-
stated.
