+// If the channel 15 is above -50% the throttle is untouched but if it is between -50% and -100%, the throttle output will be forced between -100% and -150%.

 Notes:
 - model/type/number of channels indicated on the RX can be different from what the RX is in fact wanting to see. So don't hesitate to test different combinations until you have something working. Using Auto is the best way to find these settings.
 - RX output will match the Spektrum standard TAER independently of the input configuration AETR, RETA...
 - RX output will match the Spektrum standard throw (1500µs +/- 400µs -> 1100..1900µs) for a 100% input. This is true for both Serial and PPM input. For PPM, make sure the end points PPM_MIN_100 and PPM_MAX_100 in _config.h are matching your TX ouput. The maximum ouput is 1000..2000µs based on an input of 125%.
-    - If you want to override the above and get maximum throw (old way) uncomment in _config.h the line #define DSM_FULL_THROW . In this mode to achieve standard throw use a channel weight of 84%.
+    - If you want to override the above and get maximum throw (old way) uncomment in _config.h the line #define DSM_MAX_THROW . In this mode to achieve standard throw use a channel weight of 84%.
+ - TH_KILL is a feature which is enabled on channel 15 by default (can be disabled/changed) in the _config.h file. Some models (X-Vert, Blade 230S...) require a special position to instant stop the motor(s). If the channel 15 is above -50% the throttle is untouched but if it is between -50% and -100%, the throttle output will be forced between -100% and -150%. For example, a value of -80% applied on channel 15 will instantly kill the motors on the X-Vert.

 Your help would be greatly appreciated.  If protocol reverse-engineering and dev is not your thing then any help with testing and contributing to the documentation would be amazing.  Given the number of different Tx/module hardware/RF module/protocol/model combinations the process of testing and documenting is a major bottleneck for the developers.  Anything you can do to help will free them up to do even greater things.

+# Multi-Module EEPROM
+
+The EEPROM is used to store the Multiprotocol Modules's global ID as well as details of bound receivers for certain protocols (AFHDS2A, Bugs, Devo, Walkera).
+
+On an Atmega328p module the EEPROM is a dedicated and persistent data store, separate from the 32KB of flash memory.  On the STM32 module there is no dedicated EEPROM, so EEPROM functionality is emulated in the last 2KB of flash memory.
+
+This makes it relatively easy for the STM32 EEPROM data to be accidentally erased.
+
+If the EEPROM is erased a new global ID will be generated (random for Atmega modules; the MCU UUID for STM32 modules) and models will need to be re-bound.
+
+Backups of the EEPROM data can be made so that configuration such as module ID and bound receivers can be moved between modules.  
+
+**Note:** Backups can only restored to a module with same MCU type - i.e. an Atmega backup cannot be restored to an STM32 module.
+
+The remainder of this doc is separated into sections for the STM32 and Atmega328p modules.
+
+## STM32 Module
+The EEPROM data is stored in the last 2KB of flash memory. It is read using stm32flash with the module in BOOT0 mode.
+#### Tools Needed
+* stm32flash (Download: [Windows](https://github.com/pascallanger/DIY-Multiprotocol-TX-Module-Boards/raw/master/source/stm32/tools/win/stm32flash.exe), [Linux 32-bit](https://github.com/pascallanger/DIY-Multiprotocol-TX-Module-Boards/raw/master/source/stm32/tools/linux/stm32flash/stm32flash), [Linux 64-bit](https://github.com/pascallanger/DIY-Multiprotocol-TX-Module-Boards/raw/master/source/stm32/tools/linux64/stm32flash/stm32flash), [macOS](https://github.com/pascallanger/DIY-Multiprotocol-TX-Module-Boards/raw/master/source/stm32/tools/macosx/stm32flash/stm32flash))
+* Working USB-to-Serial (FTDI) adapter
+
+#### Preparation
+Ensure that the `BOOT0` jumper is installed and the module is connected via a USB-to-Serial adapter.
+
+### Backing up the STM32 EEPROM
+The syntax of the backup command is:
+`stm32flash -r [file name] -S 0x801F800:2048 [serial port]`
+
+The `-S 0x801F800:2048` option tells stm32flash to read 2048 bytes starting at 0x801F800.
+
+Windows example:
+
+`stm32flash.exe -r C:\Temp\eeprom.bin -S 0x801F800:2048 COM4`
+
+Linux and macOS example:
+
+`stm32flash -r /tmp/eeprom.bin -S 0x801F800:2048 /dev/ttyUSB0`
+
+Output will look similar to this:

+### Restoring the STM32 EEPROM
+The syntax of the restore command is:
+`stm32flash -w [file name] -e 0 -v -S 0x801F800:2048 [serial port]`
+
+Again, the `-S 0x801F800:2048` option tells stm32flash to write 2048 bytes starting at 0x801F800.  Additionally `-e 0` tells the tool not to erase any other blocks, which will preserve the rest of the data in the module's memory.
+
+Windows example:
+
+`stm32flash.exe -w C:\Temp\eeprom.bin -e 0 -v -S 0x801F800:2048 COM4`
+
+Linux and macOS example:
+
+`stm32flash -w /tmp/eeprom.bin -e 0 -v -S 0x801F800:2048 /dev/ttyUSB0`

+
+### Erasing the STM32 EEPROM
+The syntax of the erase command is:
+`stm32flash -o -S 0x801F800:2048 [serial port]`
+
+Again, the `-S 0x801F800:2048` option tells stm32flash to erase 2048 bytes starting at 0x801F800.
+
+Windows example:
+
+`stm32flash.exe -o -S 0x801F800:2048 COM4`
+

+
+## Atmega328p Module
+The EEPROM on the Atmega328p module is a dedicated 1KB data space, separate from the main flash memory.  
+
+By default the EEPROM would be erased every time the module is flashed, but we configure the `EESAVE` bit so that the EEPROM is not erased during flashes.  This is one reason why it is crucial to set the 'fuses' on a new module using the **Burn Bootloader** command in the Arduino IDE, as described in the [documentation](Compiling.md#burn-bootloader-and-set-fuses).
+
+The module's EEPROM can be read, written, and erased using the avrdude tool.
+
+#### Tools needed
+* A USBasp device, or another Arduino programmed to function as a USBasp
+* avrdude - installed as part of the Arduino IDE installation, or [downloaded separately](http://savannah.nongnu.org/projects/avrdude)
+
+With a default Arduino IDE installation, the path to avrdude will be:
+* Windows - `C:\Program Files (x86)\Arduino\hardware\tools\avr\bin\avrdude.exe`
+* Linux - `[Arduino IDE path]/hardware/tools/avr/bin/avrdude`
+* macOS - TBD
+
+You will also need to know the path to the avrdude configuration file.  Default locations are:
+* Windows - `C:\Program Files (x86)\Arduino\hardware\tools\avr\etc\avrdude.conf`
+* Linux - `[Arduino IDE path]/hardware/tools/avr/etc/avrdude.conf`
+* macOS - TBD
+
+#### Preparation
+Connect the module using the USBasp.
+
+### Backing up the Atmega328p EEPROM
+The syntax of the backup command is:
+`avrdude -C [config file] -c usbasp -p atmega328p -U eeprom:r:[filename]:i`
+
+Windows example:
+
+`"C:\Program Files (x86)\Arduino\hardware\tools\avr\bin\avrdude.exe" -C "C:\Program Files (x86)\Arduino\hardware\tools\avr\etc\avrdude.conf" -c usbasp -p atmega328p -U eeprom:r:C:\Temp\eeprom.hex:i`

+### Erasing the Atmega328p EEPROM
+It's not possible to simply erase the EEPROM so instead we write a file which overwrites all of the content with `0xFF`.  Download the 'erase.hex' file [here](https://raw.githubusercontent.com/pascallanger/DIY-Multiprotocol-TX-Module/master/docs/erase.hex).
