| LOCAL_INTERRUPT |
Output |
1 |
AXI_CLK |
Active-high local error and status register interrupt. Asserted until
software clears the Local Error and Status Register. |
| INTERRUPT_SIDEBAND_SIGNALS |
Output |
28 |
AXI_CLK |
Signal that causes local interrupt as sideband. See Interrupt Sideband
Signals. |
| INTA_IN |
Input |
1 |
|
When the PCIe Controller is configured as an endpoint, the client
uses this input to signal an interrupt from any of its PCI functions to the root port
using legacy PCIs interrupts. This input corresponds to the PCI bus INTA. Asserting
this signal causes the PCIe Controller to send an Assert_INTx
message; de-asserting it causes the PCIe Controller to transmit a
Deassert_INTx message. |
| INTB_IN |
Input |
1 |
AXI_CLK |
When the PCIe Controller is configured as an endpoint, the client
uses this input to signal an interrupt from any of its PCI functions to the root port
using Legacy PCI Express Interrupt Delivery. This input corresponds to the PCI bus
INTB. Asserting this signal causes the PCIe Controller to send an
Assert_INTx message; de-asserting it causes the PCIe Controller
to transmit a Deassert_INTx message. |
| INTC_IN |
Input |
1 |
AXI_CLK |
When the PCIe Controller is configured as an endpoint, the client
uses this inputs to signal an interrupt from any of its PCI functions to the root port
using Legacy PCI Express Interrupt Delivery. This input corresponds to Ithe PCI bus
INT. Asserting this signal causes the PCIe Controller to send an
Assert_INTx message; de-asserting it causes the PCIe Controller
to transmit a Deassert_INTx message. |
| INTD_IN |
Input |
1 |
AXI_CLK |
When the PCIe Controller is configured as an endpoint, the client
uses this inputs to signal an interrupt from any of its PCI functions to the root port
using Legacy PCI Express Interrupt Delivery. This input corresponds to the PCI bus
INTD. Asserting this signals causes the PCIe Controller to send an
Assert_INTx message; de-asserting it causes the PCIe Controller
to transmit a Deassert_INTx message. |
| INT_PENDING_STATUS |
Input |
4 |
AXI_CLK |
When using legacy interrupts, this input indicates the PF interrupt pending
status. The i input must be set when an interrupt is pending in function i. |
| MSI_PENDING_STATUS_IN |
Input |
128 |
AXI_CLK |
These inputs provide the status of the MSI pending interrupts for the PFs
from the client to the PCIe Controller. If the MSI Pending Status In Mode
Select field is set to 1 in the Debug Mux Control 2 Register in local management
space, these pin settings determine the value read from the MSI Pending Bits Register
of the corresponding PF. Bits [31:0] belong to PF0 , bits [63:32] to PF1, and so
on. |
| INT_ACK |
Output |
1 |
AXI_CLK |
A pulse on this output indicates that the PCIe Controller has
sent an Assert_INTx or Deassert_INTx message in response to a change in
the state of one of the INTx inputs. |
| INTA_OUT |
Output |
1 |
AXI_CLK |
When the PCIe Controller is configured as a root port, this
output emulates the PCI legacy interrupt INTA. The PCIe Controller asserts
an interrupt output when it has received an Assert_INTx message from the link,
and deasserts it when it receives a Deassert_INTx message. |
| INTB_OUT |
Output |
1 |
AXI_CLK |
When the PCIe Controller is configured as a root port, this
output emulates the PCI legacy interrupt INTB. The PCIe Controller asserts
an interrupt output when it has received an Assert_INTx message from the link,
and deasserts it when it receives a Deassert_INTx message. |
| INTC_OUT |
Output |
1 |
AXI_CLK |
When the PCIe Controller is configured as a root port, this
output emulates the PCI legacy interrupt INTC. The PCIe Controller asserts
an interrupt output when it has received an Assert_INTx message from the link,
and deasserts it when it receives a Deassert_INTx message. |
| INTD_OUT |
Output |
1 |
AXI_CLK |
When the PCIe Controller is configured as a root port, this
output emulates the PCI legacy interrupt INTD. The PCIe Controller asserts
an interrupt output when it has received an Assert_INTx message from the link,
and deasserts it when it receives a Deassert_INTx message. |
