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.
