tive - link test fails) following any of the events below:
1.
Rst* deassertion
2.
Transition between link test fail to link test pass
Following this time period, the Port Status LED will switch to indication type b. In the case that the link test fails, the Port
Status LED will remain inactive and will not switch to indication type b.
Indication type b:
The Port Status LED indicates the port traffic (Transmit or Receive) activity which is a logical OR of the TxEn active and
RxDV active dynamic signals. The "monostable" function is applied to this indication type so the LED can be viewed for
a period of about 62 ms for LEDMode 0, or for about 7.5 ms for LEDMode 1, per each traffic activity. The Port Status
LED will switch to indication type a on the following cases:
1.
Rst* assertion
2.
Transition from link test pass to link test fail
17.2.2 Transmit data in progress
This signal indicates the port is transmitting data.
17.2.3 Receive data in progress
This signal indicates port receive activity.
17.2.4 Collision active
This signal indicates the port collision event detected by the port.
17.2.5 Full/Half duplex
This signal indicates the port duplex: active - full duplex, inactive - half duplex.
17.2.6 Receive Buffer Full
In order for this LED to be active, Rx Buffer Threshold must be enabled (see Table 4). This signal indicates the port
receive buffer status: active - the buffer exceeds it's programmed threshold, inactive otherwise.
17.2.7 Forwarding of unknown packets enabled
This signal indicates the port mode of forwarding unknown packets: active - forwarding unknown packets enabled,
inactive otherwise.
17.2.8 The port is configured as Sniffer
This signal indicates if the port mode is configured as a sniffer target port: active - port is a target sniffer, inactive othe r-
wise.
17.2.9 Link Fail State
This signal indicates the port link status: active - link is down, inactive - link is up.
