1 = Auto-neg speeds up internal timer
Reserved
Active low TPI link disable signal. When low, TPI still transmits
link pulses and TPI stays in good link state.
1 = HEART BEAT enable, 0 = HEART BEAT disable. HEART
BEAT function is only valid in 10Mbps mode.
1 = enable jabber function. 0 = disable jabber function
Used to login force good link in 100Mbps for diagnostic purposes.
1 = DISABLE, 0 = ENABLE.
Assertion of this bit forces the disconnect function to be bypassed.
Reserved
This bit indicates the status of the connection. 1 = valid connected
link detected; 0 = disconnected link detected.
Assertion of this bit configures LED1 pin to indicate connection
status.
