Description(Note 1)
LED[9][1]
Programs port duplex (full / half) on port 7. This is only effective if auto-negotiation is
disabled or if this end has auto-negotiation enabled and the far end has auto-
negotiation disabled.
D = Full-duplex, F/U = Half-duplex (default)
LED[9][0]
Programs port duplex (full / half) on port 8. This is only effective if auto-negotiation is
disabled or if this end has auto-negotiation enabled and the far end has auto-
negotiation disabled.
D = Full-duplex, F/U = Half-duplex (default)
LED[6][3]
Programs back-off aggressiveness for half-duplex mode
D = Less aggressive back-off, F/U = More aggressive back-off (default)
LED[6][2]
Programs retries for frames that encounter collisions.
D = Drop frame after 16 collisions, F/U = Continue sending frame regardless of the
number of collisions (default)
LED[6][1:0]
Reserved – use float configuration
LED[7][3]
Programs flow control
D = No flow control, F/U = Flow control enabled (default)
LED[7][2]
Programs broadcast storm protection.
D = 5% broadcast frames allowed, F/U = Unlimited broadcast frames (default)
LED[7][1]
Programs buffer sharing feature.
D = Equal amount of buffers per port (113 buffers), F/U = Share buffers up to 512
buffers on a single port (default)
LED[7][0]
Reserved – use float configuration
LED[8][3]
Programs address aging.
D = Aging disabled, F/U = Enable 5 minute aging (default)
LED[8][2]
Programs frame length enforcement.
D = Max length for VLAN is 1522 bytes and without VLAN is 1518 bytes
F/U = Max length is 1536 bytes (default)
LED[8][1]
Reserved
LED[8][0]
Programs half-duplex back pressure.
D = No half-duplex back pressure, F/U = Half-duplex back pressure enabled (default)
MRXD[3]
Programs port 9 speed
D = 10Mbps, F/U = 100Mbps (default)
MRXD[2]
Programs port 9 duplex
D = Half-duplex, F/U = Full duplex (default)
MRXD[1]
Programs port 9 flow control
D = Flow control, F/U = No flow control (default)
MRXD[0]
D = reserved, F/U = normal operation (default)
CTRL
EN1P
H
Enable 802.1p for all ports – this enables QoS based on the priority field in the layer
2 header.
0 = 802.1p selected by port in EEPROM
1 = Use 802.1p priority field unless disabled in EEPROM
Note: This is also controlled by the EEPROM registers (registers 4-12 bit 4). The values
in the EEPROM supercede this pin. Also, if the priority selection is unaltered in the
EEPROM registers (register 3 bits 0-7) then values above 3 are considered high priorty
and less than 4 are low priority.
MIIS[1:0]
H
MII mode selection – allows the MII to run in the following modes
MIIS
Operating mode
10
0
Disable MII interface
0
1
Reverse MII
1
0
Forward MII
1
7 wire mode (SNI)
Note 1.
All unmanaged programming takes place at reset time only. For unmanaged programming: F = Float, D = Pull-down, U = Pull-up.
