Tx Watchdog Timer
The GT-482xx includes a transmit watchdog timer for each transmit queue. For 100Mbps operation, the default
value of the timer is 63msec; the range is between 10.5 to 168msec. For 10Mbps operation, the default value of
the timer is 630msec and the range is between 105msec to 1680msec. The timer measures the time between the
transmission of two consecutive outgoing packets. When the timer expires, the GT-482xx clears the appropriate
used blocks and sends an interrupt to the CPU via Int*.
The transmit watchdog timer prevents transmission problems on one port from blocking traffic to other ports. In
managed systems, the timers also provide a mechanism to notify the CPU of a possible system problem.
The Tx Watchdog Timer can be externally disabled by holding the DisWD* pin LOW. The default is to leave the Tx
Watchdog Timer (DisWD* HIGH) enabled.
