Description
LED[1:3][3]
L
Output (after reset).
Mode 0: Link + Activity (toggle = receiving or transmitting, constant low = link,
constant high = no link).
Mode 1: Receive Activity (toggle during receiving / high = no receiving activity).
Mode 2: 100/link/act (constant low = link, toggle = act, constant high = no link).
Mode 3: Mode 3: Link + Activity (toggle = receiving or transmitting, constant low =
link, constant high = no link).
Note: Mode is set by MODESEL[3:0] ; please see description in UP “Unmanaged
Programming” section.

FFLOW1#
L
Enable force flow control feature on port 1.
Pulled up = no force flow control feature on port 1 (default).
Flow control feature is enabled and disabled by auto-negotiation.
Pulled down = enable force flow control feature on port 1 regardless of auto-negotia-
tion result.
FFLOW2#
L
Program force flow control feature on port 2.
Pulled up = no force flow control feature on port 2 (default).
Flow control feature is enabled and disabled by auto-negotiation.
Pulled down = enable force flow control feature on port 2 regardless of auto-negotia-
tion result.
LED[1][3]
Program advertise flow control feature for 10/100BaseTX ports during auto-negotia-
tion at reset time.
Pulled low = no advertise flow control during auto-negotiation.
Pulled high = advertise flow control during auto-negotiation (default).
LED[1][2]
Programs force flow control feature on port 3, incuding MII port at reset time.
Pulled low = no force flow control feature on port 3, including MII port (default).
Flow control feature is enabled/disabled by auto-negotiation result.
Pulled high = enable force flow control feature on port 3, including MII port regardless
of auto-negotiation result.
LED[1][1]
Reserved - use float configuration.
