[41CL] is it recommended to unplug module images during an upgrade?

[Sylvain Cote]

With exception of the Flash first/last block, all the other Flash blocks have a size of 64KB.
Also, one 4K word (10 bits) module becomes a 8KB in the 41CL world.
This means that one 64KB Flash block can contains 8 modules x 4K word.
Finally, a flash block cannot be partially erased.

So that is why the update must do this logic

1. copy a 64KB flash block into RAM (0x810 ... 0x817)
2. update the modules in RAM that need to be updated
3. erase the 64KB flash block
4. copy RAM (0x810 ... 0x817) to the 64KB flash block
