DA14680, Infrared and LED3

Hello,

I want the infrared controller to drive LED3 (connected to IR Led).
From DS I see:
- a GPIO can be configured with PID=4: UART_IRDA_TX - I suppose this is Infrared controller output/TX
- For LED3 I see: LED_CONTROL_REG (0x5000330C)
2,设置源(?)LED3 (LED3_SRC_SEL) as PWM4 or Breathing Timer
I do not see other configs for LED3. It appears this pin is not as a normal GPIO pin for which I could set a PID(function)

So, this means I can not drive the LED3 with the IR controller ?

Thank you,
