DM9102A

Single Chip Fast Ethernet NIC controller

When The DM9102A will use this pin to serially write

opcodes, addresses and data into the EEPROM.

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.

MA5

O Boot ROM address output signal

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.

MA7~MA9

O Boot ROM address output bus

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.

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.

MA12 /

O Boot ROM address output/ 100Mbps LED

SPEED100#

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.

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.

MA14~MA17

O Boot ROM address output bus

LED Pins (Please refer to p.11 “NOTE: LED Mode” for details.)

LINK&ACT#

O LED output pin, active low

/ ACT#

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#

O LED output pin, active low

/ FDX#

mode 0 = Full duplex LED

mode 1 = Full duplex LED

89

SPEED100#

O LED output pin, active low

/ SPEED100#

mode 0 = 100Mbps LED

mode 1 = 100Mbps LED
