表6-1. Pin Functions (continued)

NAME

TYPE⁽¹⁾

DESCRIPTION

NO.

MII Mode: COL pin can be used to drive an LED when operating in Full-

Duplex mode. Register access is required for LED configuration.

RMII Mode: This pin can be used as an LED when using register access.

RGMII Mode:This pin can be used as an LED when using register

access.

COL / GPIO2

I/O, S, PU

GPIO2: This pin can be used as a GPIO when using register access.

MII Mode: RX_D3 will remain as RX_D3 because it is required for MII

mode.

RMII Mode: RX_D3 pin can be configured to drive an LED. Register

access is required for LED configuration.

RX_D3 / GPIO3

I/O, S-PD

RGMII Mode:RX_D3 will remain as RX_D3 because it is required for

RGMII mode.

GPIO3: This pin can be used as a GPIO when using register access.

MEDIA DEPENDENT INTERFACE

TD_M

Differential Transmit Output (PMD): These differential outputs can be

automatically configured to either 10BASE-Te, 100BASE-TX, or

100BASE-FX signaling or forced into a specific signaling mode.

TD_P

RD_M

RD_P

Differential Receive Input (PMD): These differential inputs are

automatically configured to accept either 10BASE-Te, 100BASE-TX, or

100BASE-FX signaling or forced into a specific signaling mode.

POWER AND GROUND PINS

VDDIO

AVD

I/O Supply: 3.3 V, 2.5 V, or 1.8 V

Analog Supply: 3.3 V or 1.8 V

Ground

Pad

GND

Bias Resistor Connection. A 4.87-kΩ±1% resistor must be connected

from RBIAS to GND.

RBIAS

OTHER PINS

Leave Floating

This pin can be left floating when not in used. External Pull resistors are

required when LED is connected to this pin.

LED_1 / GPIO1

I/O, S-PD

(1) The definitions below define the functionality of the I/O cells for each pin.

•

Type: I - Input

Type: O - Output

Type: I/O - Input/Output

Type OD - Open Drain

Type: PD, PU - Internal Pulldown/Pullup

Type: S-PU, S-PD - Strapping Pin (All strap pins have weak internal pullups or pulldowns. If the default strap value is needed to be

changed then an external 2.2-kΩresistor should be used)
