PCI Stop
Pin Name: PCI_STOP_N
Pin Number: 134
PCI_STOP_N indicates the current target is requesting that the master stop the current transaction.
PCI Parity Error
Pin Name: PCI_PERR_N
Pin Number: 131
PCI_PERR_N indicates a data parity error between the current master and target on PCI. On a write transaction,
the target always signals data parity errors back to the master on PCI_PERR_N. On a read transaction, the
master asserts PCI_PERR_N to indicate to the system that an error was detected.
PCI System Error
Pin Name: PCI_SERR_N
Pin Number: 137
System Error is for reporting address parity errors, data parity errors on Special Cycle Command, or any other
system error where the result will be catastrophic. The PCI_SERR_N is a pure open drain and is actively driven
for a single PCI clock by the agent reporting the error. The assertion of PCI_SERR_N is synchronous to the clock
and meets the setup and hold times of all bused signals. However, the restoring of PCI_SERR_N to the
deasserted state is accomplished by a weak pull-up. Note that if an agent does not want a non-maskable interrupt
(NMI) to be generated, a different reporting mechanism is required.
PCI Parity
Pin Name: PCI_PAR
Pin Number: 140
PCI_PAR is even parity across PCI_AD[31:0] and PCI_CBE[3:0]_N. Parity generation is required by all PCI
agents. PCI_PAR is stable and valid one clock after the address phase. For data phases PCI_PAR is stable and
valid one clock after either PCI_IRDY_N is asserted on a write transaction or PCI_TRDY_N is asserted on a read
transaction. Once PCI_PAR is valid, it remains valid until one clock after the completion of the current data phase.
(PCI_PAR has the same timing as PCI_AD[31:0] but delayed by one clock.)
PCI Request
Pin Name: PCI_REQ_N
Pin Number: 103
This signal indicates to the arbiter that this agent desires use of the PCI bus.
PCI Grant
Pin Name: PCI_GNT_N
Pin Number: 98
This signal indicates to the agent that access to the PCI bus has been granted. In response to a PCI request, this
is a point-to-point signal. Every master has its own PCI_GNT_N, which must be ignored while PCI_RST_N is
asserted.
PCI Interrupt A
Pin Name: PCI_INTA_N
Pin Number: 95
Interrupt A is used to request an interrupt on the PCI bus. PCI_INTA_N is open collector and is an open drain
output.
PCI Clock Signal
Pin Names: PCI_CLK
Pin Number: 97
Clock Signal provides timing for all transactions on PCI and is an input to every PCI device. All other PCI signals
(except PCI_RST_N, and PCI_INTA_N) are sampled on the rising edge of PCI_CLK. All other timing parameters
are defined with respect to this edge.
