Added DiveO2 fatal error detection: The digital sensor provides status information which are now considered in the sanity check for sensor values. The behavior in case of an error is the same as if an analog sensor would provide a out of bounce voltage.

# How to Create From Scratch a Project for _CPU1-Upper_ Code #

The main CPU (aka. _CPU1 Discovery_) firmware is splitted in two parts:
- The proper _CPU1 Discovery_ firmware, with the main code.
- The _protected upper memory_ firmware, which is programmed during _OSTC4_ production, and contains (amongst other things) code used to upload and install firmware upgrades.

## Make a specific project ##

Follow the same procedure than for [CPU1-Discovery](Detailed CPU1-Discovery Project.md), (same processor, same includes) but include the `CPU1-Upper` source directory.
