PCI Express Interface Controller
As an initiator, the PCI Express controller supports memory read and write operations with a maximum
transaction size of 256 bytes. In addition, configuration and I/O transactions are supported if the PCI
Express controller is in RC mode. As a target interface, the PCI Express controller accepts read and write
operations to local memory space. When configured as an EP device, the PCI Express controller accepts
configuration transactions to the internal PCI Express configuration registers. Message generation and
acceptance are supported in both RC and EP modes. Locked transactions and inbound I/O transactions are
not supported.
17.1.1.1
Outbound internal platform transactions to PCI Express are first mapped to a translation window to
determine what PCI Express transactions are to be issued. A transaction from the internal platform can
become a PCI Express Memory, I/O, Message, or Configuration transaction depending on the window
attributes.
A transaction may be broken up into smaller sized transactions depending on the original request size,
transaction type, and either the PCI Express device control register [MAX_PAYLOAD_SIZE] field for
write requests or the PCI Express device control register [MAX_READ_SIZE] field for read requests. The
