TC9205M
Preliminary Data Sheet
Speed
Used by the physical layer management polling entity to configure physical layer’s
speed mode when EEPROM forced modes are selected. Additionally this bit can be
used to directly force the internal speed mode.
00 – 10M
01 – 100M
10 – 1000M
These bits should be programmed to 10M mode or 100M mode for port 5.
Duplex
Used by the physical layer management polling entity to configure physical layer’s
duplex mode when EEPROM forced modes are selected. Additionally this bit can
be used to directly force the internal duplex mode.
ForceLnk
Setting this bit to '1' will force the internal polled link status of the corresponding port
to “ON”. Default is ‘0’.
TxDisable
Setting this bit to '1' will disable the transmission MAC device, thus inhibiting
transmission on the corresponding port. Default is ‘0’.
RxDisable
Setting this bit to '1' will disable the receiving MAC device, thus inhibiting receiving
on the corresponding port. Default is ‘0’.
DisFdxFCTx
Setting this bit to '1' will disable flow control operation for full duplex mode on
transmit side (transmission of pause frames). Default is ‘0’.
DisFdxFCRx
Setting this bit to '1' will disable flow control operation for full duplex mode on
receive side (pausing frame transmission). Default is ‘0’.
DisBackPres
Setting this bit to '1' will disable flow control for half duplex mode (backpressure).
Default value is its corresponding DisBkPr pin value.
PortPriorityEn
Setting this bit to '1' will force the corresponding port to the priority set within the
PortPriority field, otherwise the pin configuration will be used.
PortPriority
This bit will set one of the four priority classes on the corresponding port.
