A.2.3 The LED Interface
The LED interface on the LSIU40SE is a four-wire arrangement that
allows the user to connect an LED harness to the board. The
GPIO0_FETCH line (maximum output low voltage 0.4 V and minimum
output low current 16 mA) is pulled low to complete the circuit when a
harness with an LED is attached. The connectors on the LSIU40SE are
J5 and J9.
