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. --wO71g9rmMq2rMVfq Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQRh246EGq/8RLhDjO14tDGHoIJi0gUCaaHgJQAKCRB4tDGHoIJi 0t3zAP99ZwKieph2a6yb8bAid0TnKtimYlllwcSNHImjVr3daQD/Q6+EdJ7XnyCc LFEaQUV9OUKHLIiECgaH5SgfHJJSUQI= =ptI0 -----END PGP SIGNATURE----- --wO71g9rmMq2rMVfq--
