This kind of application is required for some projects. 


  1. Create a new device template.
  2. Fill the name, full address and other information of the register.
  3. In the Bit Mask column, fill the Start and Stop bit of the register. For example, if only the 2nd to the 5th bits are needed, then fill “1” in the Start bit while “4” in the Stop bit. Then only the bits needed are added into the device template.
