Atom E3845 "No Reboot" Strap?

I'm trying to use the iTCO watchdog in linux running on an Atom E3845, but it is currently failing out due to not being able to unset the NO_REBOOT flag in the PM_CFG register (SIO HSUART core). The E3800 family datasheet says this bit is set on powerup if the "No Reboot" strap is sampled high, but I can't find any other references to the No Reboot strap anywhere in the datasheet. Does anyone know what or where this strap is, and where I can find more documentation on it?

Thanks,
