When LEDS1 bit (in CONFIG3 register of RTL8019AS
Page3) is 0, these 2 pins act as LED_RX & LED_TX
respectively. When LEDS1=1, these pins act as LED_CRS
& MCSB. Please refer to section 6.5 for details of the
lightening behavior of all LEDs.
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.
