NAME

FUNCTION

DIRECTION†

DEFAULT

IGLINK

Ignore link. When IGLINK is 0, the 10BASE-T PHY expects to receive link pulses

and sets the LINK bit in the GEN_sts register to 0 if they are not present. When

IGLINK is set to 1, link pulses are ignored, and the LINK bit always is set to 1.

R/W

SWAPPOLEN

Swap polarity enable. When set, SWAPPOLEN enables the PHY to reverse the

polarity of received signals after reception of seven inverted link pulses.

R/W

SWAPPOL

Swap polarity. When set, SWAPPOL forces the PHY to reverse the polarity of

received signals. Writing to SWAPPOL has no effect when SWAPPOLEN is set to

1. However, when read, SWAPPOL always reflects the current polarity setting.

R/W

SQEEN

SQE enable. Writing a 1 to SQEEN causes the 10BASE-T PHY to perform the SQE

test function at the end of packet transmission.

R/W

MTEST

Manufacturing test. When MTEST is set to 1, the PHYs are placed in manufacturing

test mode. Manufacturing test mode is reserved for Texas Instruments

manufacturing test only. Operation of the device with this bit set is undefined.

MTEST is common to all PHYs.

R/W

LINKJAB

Link jabber indication for all PHYs. When LINKJAB is set to a 1, each PHY deasserts

the LINK pin when in JABBER mode. When set to 0, JABBER has no effect on link

status. Setting this bit has no effect on the value of the LINK bit in GEN_STS register.

R/W

9–4

RESERVED

Reserved. Read as 0

NOLINKP

When NOLINKP is asserted and IGLINK is set to 1, the PHYs do not transmit link

pulses.

R/W

RESERVED

Reserved. Read as 0

INTEN

Interrupt enable. Writing a 1 to INTEN allows the TNETE2004 to generate interrupts

on the MII when the MINT bit is set to 1. INTEN does not affect test interrupts. INTEN

is common to all PHYs; changing it on one PHY changes it on all PHYs.

R/W

TINT

Test interrupt. Writing a 1 to TINT causes the PHY to generate an interrupt on the

MII. Writing a 0 to TINT causes the PHY to stop generating an interrupt on the MII.

This test function is totally independent of INTEN and the MINT bit. TINT is used for

diagnostic test of the MII-interrupt function. TINT is common to all PHYs.

R/W

† RO = read only, R/W = read/write
