DM9102A
Single Chip Fast Ethernet NIC Controller
MA0
O Boot ROM Address Output Line/WOL Mode Selection
This multiplexed pin acts as boot ROM address output bus
during normal operation. When RST# is active, it is used to
pull up or down externally through a resister to select WOL
High active or LOW active (WMODE)
0 = WOL high active (default)
1 = WOL low active
MA1
O Boot ROM Address Output Signal
MA2
O Boot ROM Address Output Signal
MA3/EEDO
O Boot ROM Address Output/EEPROM Data Out
This is a multiplexed pin used by MA3 and EEDO
When the boot ROM is not active, the DM9102A uses this
pin to serially write op-codes, addresses and data into the
EEPROM
MA4/EECK
O Boot ROM Address Output/EEPROM Serial Clock
This is a multiplexed pin used by MA4 and EECK
When the boot ROM is not active, the DM9102A uses this
pin as the clock for the EEPROM data transfer
MA5
O Boot ROM Address Output Signal/EEPROM Chip Select
This is multiplexed pin used by MA4 and EECS
When the DM9102A is configured to use external PHY
mode, this pin is used as the EEPROM chip select
MA6~MA9
O Boot ROM Address Output Bus
MA10/LINK&ACT# O Boot ROM Address Output Signal/Link & Active LED
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 a led defined as LED Pins
descriptions
MA11/FDX#
O Boot ROM Address Output/Full-duplex LED
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 a led defined as LED Pins
descriptions
MA12 /
O Boot ROM Address Output/ 100Mbps LED
SPEED100#
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 a led defined as LED Pins
descriptions
MA13/SPEED10# O Boot ROM Address Output Signal/10Mbps LED
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 a led defined as LED Pins
