Internal Registers
This section describes the internal registers in FW323, including both PCI configuration registers and OHCI regis-
ters. All registers are detailed in the same format; a brief description for each register, followed by the register offset
and a bit table describing the reset state for each register.
A bit description table indicates bit-field names, a detailed field description, and field access tags.
Table 2 describes the field access tags.

PCI Configuration Registers
Table 3 illustrates the PCI configuration header that includes both the predefined portion of the configuration
space and the user definable registers.

Description
Field may be read by software.
Field may be written by software to any value.
Field may be set by a write of 1. Writes of 0 have no effect.
Field may be cleared by a write of 1. Writes of 0 have no effect.
Field may be autonomously updated by the FW323.
