Ball Function Description

1 = force port 2 to 100BT if P2ANEN = 0

0 = force port 2 to 10BT if P2ANEN = 0

1 = port 2 default to full duplex mode if P2ANEN = 1 and

auto-negotiation fails. Force port 2 in full duplex mode if

P2ANEN = 0.

0 = port 2 default to half duplex mode if P2ANEN = 1 and

auto-negotiation fails. Force port 2 in half duplex mode if

P2ANEN = 0.

1 = always enable (force) port 2 flow control feature

0 = port 2 flow control feature enable is determined by auto-

negotiation result.

Port 2 LED indicator

Note: Internal pull-down is weak; it will not turn ON the LED.

See description in pin 4.

LED display mode select

See description in pins 1 and 4.

Port 1 LED indicator

Note: An external 1K pull-down is needed on this pin if it is

connected to a LED. The 1K resistor will not turn ON the

LED.

See description in pin 1.

Strap pin for RMII Mode

0 = Disable

1 = Enable

After reset, this pin has no meaning and is a no connect.

Hardware pin overwrite

0 = Disable. All strap-in pins configurations are overwritten by

the EEPROM configuration data

1 = Enable. All strap-in pins configurations are overwritten by

the EEPROM configuration data, except for register 0x2C bits

[7:5], (port 2: auto-negotiation enable, force speed, force

duplex).

Port 2 Auto MDI/MDI-X

PD (default) = enable

PU = disable

Port 2 MDI/MDI-X setting when auto MDI/MDI-X is disabled.

PD (default) = MDI-X (transmit on TXP2 / TXM2 pins)

PU = MDI, (transmit on RXP2 / RXM2 pins)

1 = enable auto-negotiation on port 1

0 = disable auto-negotiation on port 1

1 = force port 1 to 100BT if P1ANEN = 0

0 = force port 1 to 10BT if P1ANEN = 0

1 = port 1 default to full duplex mode if P1ANEN = 1 and

auto- negotiation fails. Force port 1 in full-duplex mode if

P1ANEN = 0.

0 = port 1 default to half duplex mode if P1ANEN = 1 and

auto- negotiation fails. Force port 1 in half duplex mode if

P1ANEN = 0.
