EDPWRDOWN
Enable the Energy Detect Power-Down mode:
0 = Energy Detect Power-Down is disabled
1 = Energy Detect Power-Down is enabled
RESERVED
FARLOOPBACK
Enables far loopback mode (i.e., all the received packets are sent back
simultaneously (in 100BASE-TX only)). This mode works even if the Isolate
bit (0.10) is set.
0 = Far loopback mode is disabled
1 = Far loopback mode is enabled

information.
RESERVED
ALTINT
Alternate Interrupt Mode:
0 = Primary interrupt system enabled (Default)
1 = Alternate interrupt system enabled
Refer to
information.
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
