DM9102A
Single Chip Fast Ethernet NIC controller
Final
11
Version: DM9102A-DS-F03
August 28, 2000
When The DM9102A will use this pin to serially write
opcodes, addresses and data into the EEPROM.
79
MA4/EECK
O
Boot ROM address output/EEPROM serial clock
This is multiplexed pin used by MA4 and EECK .
This pin provides the clock for the EEPROM data transfer.
80
MA5
O
Boot ROM address output signal
81
MA6/SELROM
O/LI
Boot ROM address output/Multiplex or Direct mode selection
This multiplexed pin acts as boot ROM address output bus
during normal operation. When RST# is active, it is used as
multiplex and direct mode selection :
0 = Boot ROM interface is in multiplex mode (default)
1 = Boot ROM interface is in direct mode.
83,84,85
MA7~MA9
O
Boot ROM address output bus
87
MA10/LINK&ACT#
O
Boot ROM address output signal/Link & Active LED
In DIR mode, this pin represents the Boot ROM address bit
10 when at the time of boot ROM operation. When Boot
ROM is not accessed, this pin acts as traffic-and- link led in
LED MODE 0 or traffic led in LED MODE 1.
88
MA11/FDX#
O
Boot ROM address output/Full-duplex LED
In DIR mode, this pin represents the Boot ROM address bit
11 when at the time of boot ROM operation. When Boot
ROM is not accessed, this pin acts as full-duplex led.
89
MA12 /
SPEED100#
O
Boot ROM address output/ 100Mbps LED
In DIR mode, this pin represents the Boot ROM address bit
12 when at the time of boot ROM operation. When Boot
ROM is not accessed, this pin acts as speed-100 led.
90
MA13/SPEED10#
O
Boot ROM address output signal/10Mbps LED
In DIR mode, this pin represents the Boot ROM address bit
13 when at the time of boot ROM operation. When Boot
ROM is not accessed, this pin acts as speed-10 led.
91,92,93,

Description
87
LINK&ACT#
/ ACT#
O
LED output pin, active low
mode 0 = Link and traffic LED. Active low to indicate normal
link, and it will flash as a traffic LED when transmitting or
receiving.
mode 1 = traffic LED only
88
FDX#
/ FDX#
O
LED output pin, active low
mode 0 = Full duplex LED
mode 1 = Full duplex LED
89
SPEED100#
/ SPEED100#
O
LED output pin, active low
mode 0 = 100Mbps LED
mode 1 = 100Mbps LED
