It's better for VM pin groups of 9,10 and 21,22 to short-circuit on the
PCB pattern. If cannot, check into transitional characteristics of total
application circuit including two motors. Through low impedance
materials, the possibility of causing some unexpected malfunctions
is incontrovertible.

Description of Blocks
1.
Power-Saving Function
A power-saving function is included, which allows the system to save power when not driving the motor. The voltage
level on this pin should be set high so as to keep the operation mode. (See the Electrical Characteristics; p.4/14)
Motor Control Input
(a) IN1A, IN1B, IN2A and IN2B Pins
Logic level controls the output logic of H-Bridge.
(See the Electrical Characteristics; p.4/14, and I/O Truth Table; p.7/14)
(b) PWM Pin
Logic level sets the IN/IN or EN/IN drive mode.
(See the Electrical Characteristics; p.4/14 and I/O Truth Table; p.7/14)
3.
VM Terminal
Each H-bridge can be controlled independently. Take into consideration that each VM terminal (9, 10, 21 and 22pin) is
short-circuited internally.
(See the Block Diagram; p.2/14)

Caution:
Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.
