Register 70. PHYCN: Physical Layer Control Register
Important Note: When using auto-negotiation, the auto-negotiation enable bit, AUTONEG (PHYCF.4), must
be set to “1” prior to
setting PHYEN, TXEN, and RXEN to 1. To restart auto-negotiation,
clear one of the three enable bits (PHYEN, TXEN, and RXEN) to “0” then set it back to “1”.
Bit 7:
PHYEN: Physical Layer Enable
0: The physical layer is placed in a low-power state with limited functionality.
1: The physical layer is placed in a normal power state and is fully functional.
Bit 6:
TXEN: Transmitter Enable
0: Physical Layer’s transmitter is placed in a low-power state. Packet transmission and Link Pulse
Generation Functions are disabled.
1. Physical layer’s transmitter is enabled.
Bit 5:
RXEN: Receiver Enable
0: Physical layer’s receiver is placed in a low-power state. Packet reception is disabled.
1: Physical layer’s receiver is enabled.
Bit 4:
DPLXMD: Full-duplex Mode Enable Bit
Note: This bit is read-only when Auto-Negotiation is enabled.
0: Half-duplex mode is selected.
1: Full-duplex mode is selected.
Bit 3:
LBMD: Loopback Mode Enable Bit
Note: Loopback mode is automatically disabled if a jabber condition is detected.
0: Loopback mode is disabled.
1: Loopback mode is enabled.
Bit 2:
LPRFAULT: Link Partner Remote Fault (Local Fault) Indicator
0: Normal operation.
1: The link partner has detected a link fault and has sent notification during auto-negotiation. This
condition can occur if the local transmitter is disabled and link pulses are no longer generated.
Bit 1:
POLREV: Polarity Reversed Indicator
0: Incorrect link polarity has not been detected.
1: Incorrect link polarity detected. Link polarity has been automatically reversed.
Bit 0:
LINKSTA: Link Status Indicator
0: Link is bad.
1: Link is good.
