| Description | Specifies whether or not Link Integrity Test Function is
enabled for the port as specified by the 10BaseT Standard.
When the link test function is enabled, the absence of the
Link Test pulses and receive data on the port will cause the
port to go into a Link Fail state. In this state, the data
transmission, data reception and collision detection functions
are disabled until valid data or 4 consecutive Link Test
pulses appear on RXD+/- pair of the port.
With the Link Integrity Test Function disabled, the data
driver, receiver and collision detection remain enabled
irrespective of the presence or absence of data or Link Test
pulses on the port. |
