6. Register Definition

6.1 PCI Configuration Registers

The definitions of PCI Configuration Registers are based on

the PCI specification revision 2.2 and it provides the

initialization and configuration information to operate the PCI

interface in the DM9102D. All registers can be accessed

with byte, word, or double word mode. As defined in PCI

specification

2.1,

read

accesses

to

reserve

or

unimplemented registers will return a value of “0.” These

registers are to be described in the following sections.

The default value of PCI configuration registers after reset.

Key to Default

In the register description that follows, the default column

takes the form <Reset Value>

Where：

<Reset Value>:

1

Bit set to logic one

0

Bit set to logic zero

X

No default value

<Access Type>:

RO = Read only

RW = Read/Write

R/C: means Read / Write & Write "1" for Clear.
