Actually no, I take my ack back. This doesn't make sense to me, I think
the wording needs improvement. I think it might be as little as:
	If enabled as an output, the GPIO pin number must be in range of
	[0, 7]. [0, 3] are for local GPIO data and [4, 7] for GPIO data coming
	from remote compatible deserializer.
