Fig.15 shows a 16 ports HUB with four TMC2005s connected by open–drain ports. When assigning two ports for
cascade connection to the same TMC2005, the number of TMC2005s for serial connection can be reduced to the
number of HUBs plus two.

When connecting TMC2005 by open-drain output on a board, connecting TMC2005s must be four or less,
and the data rate must be 5Mbps or slower. The pattern of open-drain output has to be as short as possible
