Description

MD0/EEDI

Boot ROM data input/EEPROM data in

This is multiplexed pin used by EEDI and MD0.

When boot ROM is selected, it acts as boot ROM data input.

When ROMCS select the EEPROM, the DM9102A will read

the contents of EEPROM serially through this pin.

MD1~MD7

Boot ROM data input bus

MD1 is also a reset latch pin. It is Boot ROM address and

data bus when normal operation. When at power on reset, it

is used to pull up or down externally through a resister to

select the WOL as pulse orlevel signal.

0 = WOL pulse mode (default)

1 = WOL level mode

MD2 is also a reset latch pin. It is Boot ROM address and

data bus when normal operation. When at power on reset, it

is used to pull up or down externally through a resister to

select the PME as pulse or level signal.

0 = PME pulse mode (default)

1 = PME level mode

MD7 is also a reset latch pin. It is Boot ROM address and

data bus when normal operation. When at power on reset, it

is used to pull up or down externally through a resister to

select LED mode.

0 = LED mode 0 (default)

1 = LED mode 1

ROMCS

Boot ROM or EEPROM chip selection.

MA0/WMODE

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/PCIMODE#

O, LI

Boot ROM address output signal/PCI mode selection

This multiplexed pin acts as a boot ROM address output

signal during normal operation. When RST# is active, it acts

as the input system type. If the DM9102A is used in a

CardBus system, this pin should be connected to a pull-up

resistor; otherwise, the DM9102A consider the host as a PCI

system.

0 = PCI mode (default)

1 = CardBus mode

MA2

Boot ROM address output signal

MA3/EEDO

Boot ROM address output/EEPROM data out

This is multiplexed pin used by MA3 and EEDO.
