5. Register Descriptions
The registers in RTL8019AS can be roughly divided into two groups by their address and functions
-- one for NE2000, the other for Plug and Play (PnP).
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 RTL8019AS
defines some registers for software configuration and feature enhancement.
