Atom E3845 "No Reboot" Strap?

[GDoor]

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,
