Bugfix Empty menu:
In previous version an empty menu was shown sporadically. After pressing back button the menu was shown correctly again. Potential root cause is the call of the Set Top/Bottom Frame function while updating the cursor position. To handle multible updated is previous toggle bugger has been changed into a ringbuffer allowing to send several update frames after each other.
Beside this some old debug code has been removed.

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