2.4 LEDs

User LEDs are provided on the evaluation board – two red and two green. An RGB LED is also included
and this can be enabled by changing the position of JLED1.
LEDs are powered by VIO and are active low. The GPIO should be enabled for high drive when sinking
current for the LEDs. The LEDs can be completely removed from the circuit by breaking the
associated jumper.
