R/W Description
R/W
Controls output of EXOUT1 (Ethernet controller
function) and TEND1 (other function).
0: TEND1 (other function) is selected.
1: EXOUT1 (Ethernet controller function) is selected.
R
Reserved
This bit is always read as 0. The write value should
always be 0.

function) and TEND0 (other function).
0: TEND0 (other function) is selected.
1: EXOUT0 (Ethernet controller function) is selected.
R
Reserved
This bit is always read as 0. The write value should
always be 0.
R/W
