DP83867IR: LED pin

Part Number: DP83867IR

Hello team,

Datasheet 8.5.2 states there are four pins for LED; LED_0, LED_1, LED_2 and RXD7/GPIO.

I think RXD7/GPIO can be for LED_3 pin and this is done by setting 0x0171[15:12] to 0110.

However looking at other GPIO Mux control register such as 0x0171 and 0x0172, it looks like all other GPIO pins can also be set as LED_3.

I thought RXD7 is only pin for LED_3 by description of datasheet 8.5.2 though, can all other GPIO pins also act as LED pin? 

I would like to know why datasheet 8.5.2 mentions only specific RXD7/GPIO without mentioning other configurable GPIO pins.

Best regards,
