Instruction set

3 bytes are always sent as a block:

first Byte = Lower address	00AAAAAA	Address 0-63
second Byte = High Address and Switch Group 1	0100AAAA	Address 64-1023
second Byte = High Address and Switch Group 2	0110AAAA	Address 64-1023
third Byte = Command light with the bit sequence	10CCCCCC	Output 1-5
third Byte = Command Motor with the bit sequence	11MM1MMM	Speed ​​step 0-28

With byte 1 and 2 you can address up to 1023 cars.
In addition, the function group is switched over with it.
