Hi all,

     I have a really weird problem, no matter what I do the M24SR creates a 1s sqaure wave on the GPO pin and when I say 1 second it is excatly 500ms off and 500ms on.  I have set the GPO to be HIGH Impedance for both RF and I2C comms and it still does it, I have killed all power to it and then re-applied it and same difference. Its like I've managed to discover a test mode which is undocumented as far as I can tell. Has anyone found this before and if so how can I get the device out of this mode?  please find first bit of the system file data attached

 

Thanks for looking

Luke
