8.3 LED Drivers
CSR8615 QFN includes a 3-pad synchronised PWM LED driver for driving RGB LEDs for producing a wide range
of colours. All LEDs are controlled by firmware.
The terminals are open-drain outputs, so the LED must be connected from a positive supply rail to the pad in series
with a current-limiting resistor.

Note:
The supply domain in Section 1.2 for LED[2:0] must remain powered for LED functions to operate.
The LED current adds to the overall current. Conservative LED selection extends battery life.
