A.3.3 The LED Interface

The LED interface on the SYM22801 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 SYM22801 are

J5 and J9.
