3.2.3 The LED Interface
The LSI20160 LED interface is a four-wire arrangement that allows you
to connect an LED harness to the board. The GPIO0_FETCH line has a
maximum output low voltage of 0.4 V and minimum output low current of
16 mA. It is driven low to complete the circuit when a harness with an
LED is attached. The J3 connector provides the LED connection on the
LSI20160.
Table 3.5 lists the signal and pin numbers for the LED
interface.
