Message Unit (I2O) Registers

Message unit registers are described in Section 9.12, “Message Unit (I2O),” on page 9-66.

9.11.1.2

DMA Controller Registers

DMA registers are described in Section 9.13, “DMA Controller,” on page 9-86.

9.11.1.3

PCI Outbound Translation Address Registers (POTAR

The PCI outbound translation address registers (POTARx), shown in Figure 9-17, select the starting

addresses in PCI address space for locally generated transactions that hit within the outbound translation

windows. The new translated address is created by concatenating the transaction offset to this translation

address. Refer to Section 9.10.2.2, “PCI Outbound Translation.”
