(10) Setting output current.
As the output circuit of M54679SP is designed by the bipolar type NPN transistors, the current that go through the
motor coil is smaller about 15 mA (typical) than the current that go through the current sensing resistor. This is caused
by the base current of the power transistors.
Therefore, be aware this base current when the output current is set.

(11) Power GND terminal.
Power GND is connected the anodes of flywheel diodes of bottom side. When the output H-bridge power stage goes to
ON, as the flyback current go through this GND terminal, minimize the wire resistor of this GND on the board.
