  *  Header Frame:
  *  1 - CRC is last after payload
  *  Ex1 - If Len=0 then CRC is #4
  *  Ex2 - If Len=1 then CRC is #5 and payload is #4
  *  2 - If CRC is not the last by in the frame
  *  then there is padding 0x00 to make the frame 8 byte fix
+ *
  *  Tail Frame:
  *  3 - Partial frames only have Payload and CRC ( and padded)
