CPU90F Board (Optional)
A 133MHz Pentium CPU is used to perform I/O initialization within the board, communication
with an upper-layer host, and control of the LAN.
16 MB of main memory (two 8 MB SIMMs) is installed.
Its LAN controller supports IEEE 802.3-compliant 100BASE-TX/10BASE-T, and auto-negoti-
ates the speed for automatic switching; as such, only one RJ-45 connector is provided.
On this board, eight software control LEDs and six LAN communication status indication
LEDs are located.
Of them, the LAN communication status indication LEDs and their block diagram are illus-
trated below.
