Link Pulse Enable
1 = Transmission of link pulses enabled
0 = Link pulses disabled, good link condition forced
This bit is valid only in 10Mbps operation
Heartbeat Enable
1 = Heartbeat function enabled
0 = Heartbeat function disabled
When the DM9161CI is configured for full duplex operation, this bit will
be ignored (the collision/heartbeat function is invalid in full duplex
mode)
Squelch Enable
1 = Normal squelch
0 = Low squelch
Jabber Enable
Enables or disables the Jabber function when the DM9161CI is in
10BASE-T full duplex or 10BASE-T transceiver Loopback mode
1 = Jabber function enabled
0 = Jabber function disabled
10BASE-T GPSI Mode ( Default value depend on #pin34 strap
condition)
1 = 10BASE-T GPSI mode selected (#pin34 pull down)
0 = 10BASE-T MII mode selected (#pin34 pull up, default)
GPSI mode is not supported for 100Mbps operation
Reserved
Read as 0, ignore on write
Polarity Reversed
When this bit is set to 1, it indicates that the 10Mbps cable polarity is
reversed. This bit is automatically set and cleared by 10BASE-T
module
