Activated work gas for (p)scr mode: In previous version setting of change depth for work (travel) gases was not possible. For (p)scr operation this is not possible. Work gases will not be considered for deco calculation. In addition the first gas will be handled as "deco" gas. This allows switching back to the first gas in case the current gas becomes no longer breathable (ppo2 low).

# 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.
