P13TXE
Port 14 Speed Force Mode Setup:
During RST# rising edge, if
EnP14ForceMode = High, this pin acts as port 14s speed force mode
setup pin set as below:
1: Force 100 Mbps speed. (default)
0: Force 10 Mbps speed.
Port 15 Force Mode Setup Enable:
Pulled high upon reset will
enable port 15 to set flow control, duplex mode and speed by
P15FCTRL, P15DUPLEX and P15SPEED pins separately. Otherwise,
the setup will depends on port 15s auto-negotiation results.
1: Enable force mode setting
0: Disable force mode setting (default)
P14TXD0
Port 15 Flow Control Force Mode Setup:
During RST# rising
edge, if EnP15ForceMode = High, this pin acts as port 15s flow
control force mode setup pin set as below:
1: Force enable flow control (default)
0: Force disable flow control
P15TXD0
Port 15 Duplex Force Mode Setup:
During RST# rising edge, if
EnP15ForceMode = High, this pin acts as port 15s duplex force mode
setup pin set as below:
1: Force full duplex mode (default)
0: Force half duplex mode
P15TXE
Port 15 Speed Force Mode Setup:
During RST# rising edge, if
EnP15ForceMode = High, this pin acts as port 15s speed force mode
setup pin set as below:
1: Force 100 Mbps speed (default)
0: Force 10 Mbps speed
P9TXE
Enable Broadcast Storm Filtering Control:
Pulled high upon reset
will enable the broadcast storm control function. Pulled low upon
reset will disable the broadcast storm control function.
P8TXD0
Enable 802.1D specified reserved group MAC addresses frame
filtering:
When network control frames are received with the destination
MAC address as a group MAC address: (01-80-C2-00-00-03 ~
01-80-C2-00-00-0F), the RTL8316 will drop the frames if the
EnCtrlFrameFilter is set. Otherswise , it will be flooded. The value of
EnCtrlFrameFilter is trapped on the power on reset.
1: Enable drop
0: Disable drop (default)
P10TXE
Enable Back pressure flow control function
During hardware reset, the pull-high/low value will control the Back
pressure flow control function.
1: Enable back pressure (default)
0: Disable back pressure
P9TXD0
Enable Full Duplex 802.3x Flow Control:
Pulled high upon reset
will enable the full duplex IEEE802.3x flow control function. The
flow control ability will be written to management register 4 of the
PHY device once (and only once) after power-on reset, for
advertising.
Pulled low upon reset will disable the full duplex flow control
function.
P1TXD0
Enable Port Trunk 0:
Pulled high upon reset will enable port trunk
0 which consists of ports 0,1,2,3.
P2TXE
Enable Port Trunk 1:
Pulled high upon reset will enable port trunk
1 which consists of ports 4,5,6,7.
P2TXD0
Enable Port Trunk 2:
Pulled high upon reset will enable port trunk
2 which consists of ports 8,9,10,11.
P3TXE
Enable Port Trunk 3:
Pulled high upon reset will enable port trunk
3 which consists of ports 12,13,14,15.
