10.2
Each SSD signal is the output pin of a half bridge, designed to source or sink current. The H-bridge pins
drive the sine and cosine coils of a stepper motor to provide four-quadrant operation. The SSD is capable
of multiplexing between stepper motor A and stepper motor B if two motors are connected.
10.2.1
These pins interface to the cosine coils of a stepper motor to measure the back EMF for calibration of the
pointer reset position.
10.2.2
These pins interface to the sine coils of a stepper motor to measure the back EMF for calibration of the
pointer reset position.
