* **bitmask**
  * Parts of the device name that are allowed to be changed:
    * bit 0 (LSB): Arbitrary Address Capable
    * bit 1: Industry Group
    * bit 2: System Instance
    * bit 3: System
    * bit 4: Function
    * bit 5: Function Instance
    * bit 6: ECU Instance
    * bit 7 (MSB): Manufacturer Code
