GPIO sleep cleanup: During bringup of OSTC5 HW usage of new GPIO pins was introduced. To avoid not needed active GPIO pins during sleep some cleanup has been done (pins are only active if needed by new hardware, clocks deactivated during sleep etc.)

# 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.
