Anyone know which pin is the XPD pin? I'm using an ESP-12 board
Sparkfun's breakout board gets it from somewhere on the chip but I can't find mention of it elsewhere

Its GPIO16 i think.

Yes, it is ...

Thanks I was trying that pin with a sleep arrangement where that pin is tied to reset and it takes the execution to the start of the program when the sleep time is up . However it does not seem to be working for me . Is there anything needed code wise to prepare the pin as XPD or does it need a resistor ?Seems to be reset if not connected and many resets if connected.
