9500/9600 or similar G8 31.3344M crystal output enable pin source location
Does anyone know the source location of the output enable (oe) pin for the G8/G3 crystal is.

I have a board that was working but now the OE is always LOW on just this crystal and measuring from that pin to any of the others results in an open reading.

I've checked the 9600 schematics and it's labelled as C31M_OE however the only reference to this is in test points. I assume it connected via a resistor to 5v put can't locate it.

Any suggestions were to look would be appreciated as there are no visible traces from this pin.
