Description
No connect
Hardware pin overwrite
0 = Disable. All strap-in pins configurations are overwritten by
the EEPROM configuration data
1 = Enable. All strap-in pins configurations are overwritten by
the EEPROM configuration data, except for register 0x2C bits
[7:5], (port 2: auto-negotiation enable, force speed, force
duplex).
Port 2 Auto MDI/MDI-X
PD (default) = enable
PU = disable
Port 2 MDI/MDI-X setting when auto MDI/MDI-X is disabled.
PD (default) = MDI-X (transmit on TXP2 / TXM2 pins)
PU = MDI, (transmit on RXP2 / RXM2 pins)
1 = enable auto negotiation on port 1
0 = disable auto negotiation on port 1
1 = force port 1 to 100BT if P1ANEN = 0
0 = force port 1 to 10BT if P1ANEN = 0
1 = port 1 default to full duplex mode if P1ANEN = 1 and auto
negotiation fails. Force port 1 in full-duplex mode if P1ANEN
= 0.
0 = port 1 default to half duplex mode if P1ANEN = 1 and auto
negotiation fails. Force port 1 in half duplex mode if P1ANEN
= 0.
1 = always enable (force) port 1 flow control feature
0 = port 1 flow control feature enable is determined by auto
negotiation result.
