    Why not just use the on-chip RAM...?

    Is there a register on the cortex m3 that can be used like static ram?

    We would like to find a user registr that retains it value through a process/watchdog reset.

    Is there such a beast?

    Have a look at the ''backup registers''. These retain their values through a reset (and power down if battery backed). See the firmware lib for examples.

    They are powered from the same supply that powers the RTC.
