5. REGISTER DESCRIPTIONS

The registers in RTL8029AS controller can be roughly divided into two groups by their address and

functions -- one for NE2000, the other for PCI Configuration Space.

5.1. Group 1: NE2000 Registers

This group includes 4 pages of registers which are selected by bit PS0 & PS1 in the CR register.

Each page contains 16 registers. Besides those registers compatible with NE2000, the RTL8029AS

controller defines some registers for software configuration and feature enhancement.
