GMII/RGMII/MII Receive Data

Please see the pin description of pin 39.

RX_ER

GMII and MII Receive Error

RX_ER shares the same pin with PHY_ADDR2.

Not used.

CRS

IPH/O

GMII/MII Carrier Sense

It asserts during either the transmission or the

reception.

CRS shares the same pin with PHY_ADDR1.

COL

IPH/O

GMII/MII Collision

If IP1001 operates in half mode, it asserts when both

transmission and reception are running. If IP1001

works in full duplex mode, COL is always idle (logic

low).

COL shares the same pin with PHY_ADDR0.
