   * 0 Hard coded, minmal program and eeprom usage.
   * 1 Stored in fixed eeprom locations, rewritten from flash if corrupt.
   *   This allows parameter changes using a hardware programmer or custom application code.
   *   Corruption test is based on channel verify so get the channel before anything else!
   * 2 Obtained from eeprom using the general settings manager and read from program flash if not present.
   *   Useful for for testing builds without wearing out flash memory.
   * 3 Obtained from eeprom using the settings manager and rewritten from flash if not present.
   *   This ensures all parameters are present in upper eeprom flash.
   *
   * Note the parameters in this file can be changed without forcing a complete rebuild.
