5.35. CS Configuration Register (Offset 0074h-0075h, R/W)
Table 35. CS Configuration Register
Description/Usage
1: Auto negotiation to speed up internal timer
Reserved.
Active low TPI link disable signal. When low, TPI still transmits
link pulses and TPI maintains a good link state.
The HEARTBEAT function is only valid in 10Mbps mode.
1: HEARTBEAT enable
0: HEARTBEAT disable
1: Enable jabber function
0: Disable jabber function
Used to login a forced good link at 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 the LED1 pin to indicate
connection status.
Reserved.
Bypass Scramble.
