BITS

DESCRIPTION

TYPE

DEFAULT

15:14

RESERVED

EDPWRDOWN

Enable the Energy Detect Power-Down mode:

0 = Energy Detect Power-Down is disabled

1 = Energy Detect Power-Down is enabled

R/W

12:10

RESERVED

FARLOOPBACK

Enables far loopback mode (i.e., all the received packets are sent back

simultaneously (in 100BASE-TX only)). This bit is only active in RMII mode.

This mode works even if the Isolate bit (0.10) is set.

0 = Far loopback mode is disabled

1 = Far loopback mode is enabled

Refer to Section 3.8.9.2, "Far Loopback," on page 43 for additional

information.

R/W

8:7

RESERVED

ALTINT

Alternate Interrupt Mode:

0 = Primary interrupt system enabled (Default)

1 = Alternate interrupt system enabled

Refer to Section 3.6, "Interrupt Management," on page 34 for additional

information.

R/W

5:2

RESERVED

ENERGYON

Indicates whether energy is detected. This bit transitions to “0” if no valid

energy is detected within 256ms. It is reset to “1” by a hardware reset and

is unaffected by a software reset. Refer to Section 3.8.3.2, "Energy Detect

Power-Down," on page 40 for additional information.
