635+SCAB+ATX GPIO question

Hi All,

I just ordered a 635+SCAB+ATX power connection.
I read in the SCAB datasheet that GPIO1 to GPIO3 are taken for ATX control.
Can one still use GPIO0? The reason I'm asking is that it appears that the plug of the ATX cable covers the GPIO0 pin but is unpopulated. I was planning on using it to drive a relay to turn my CCFL on or off.

Thanks

Yes, you should be able to do that. Be sure to only use 0% or 100% for the setting. In between we use a PWM that would not work well with a relay.
