Description

LED display mode select

See description in pins 1 and 4.

Switch MII transmit enable

Switch MII transmit data bit 3

Switch MII transmit data bit 2

Switch MII transmit data bit 1

Switch MII transmit data bit 0

Switch MII transmit error

Switch MII transmit clock (MII and SNI modes only)

Output in PHY MII mode and SNI mode

Input in MAC MII mode

Reference Clock (RMII mode only)

Input for 50MHz +/- 50ppm system clock

Note: In RMII mode, pin X1 is pulled up to VDDIO supply with

a 10K resistor and pin X2 is a no connect.

Digital ground

3.3V digital VDD

Switch MII receive clock.

Output in PHY MII mode

Input in MAC MII mode

Switch MII receive data valid

Switch MII receive data bit 3

Strap option: switch MII full-duplex flow control

PD (default) = disable

PU = enable

Switch MII receive data bit 2

Strap option: switch MII is in

PD (default) = full-duplex mode

PU = half-duplex mode

Switch MII receive data bit 1

Strap option: Switch MII is in

PD (default) = 100Mbps mode

PU = 10Mbps mode

Switch MII receive data bit 0

Strap option: switch will accept packet size up to

PD = 1536 bytes (inclusive)

PU = 1522 bytes (tagged), 1518 bytes (untagged)

Switch MII collision detect

Switch MII carrier sense

Note:

1. P = Power supply.

Gnd = Ground.

I = Input.

O = Output.

Ipd/O = Input w/ internal pull-down during reset, output pin otherwise.

I/O = Bi-directional.
