Transmit jabber timer time-out.
1: when the transmit jabber timer expires. The
transmit processor will enter the stop state and
TO (bit 14 of TDES0, transmit jabber time-out
flag) will be asserted.
Transmit descriptor unavailable.
1: when the next transmit descriptor can not be
obtained by the STE10/100A. The transmission
process is suspended in this situation. To restart
the transmission process, the ownership bit of
the next transmit descriptor should be set to
STE10/100A and, if the transmit automatic
polling is not enabled, a transmit poll demand
command should then be issued.
Transmit process stopped.
1: while transmit state = stop
Transmit completed interrupt.
1: set when a frame transmission completes with
IC (bit 31 of TDES1) asserted in the first transmit
descriptor of the frame.

SQE disable
0: enable SQE function for 10BASE-T operation.
The STE10/100A provides SQE test function for
10BASE-T half duplex operation.
1: disable SQE function.
