Overview
This section lists the main features for Stepper Motor Controller.
Features of the Stepper Motor Controller:

Four high-current output drivers: Stepper Motor Controller provides four driver outputs with high current
driving capability. Two motor coils can be connected directly to four stepper motor controller pins. The
motor rotation is controlled by a combination of the PWM Pulse Generator and selector logic circuits.

Two PWM Pulse Generators with 10-bit/8-bit operation mode (selected by software):
−
For the PWM pulse width in 8-bit operation mode, the duty can be specified within the range from
0% to 99.6%.
−
For the PWM pulse width in 10-bit operation mode, the duty can be specified within the range from
0% to 99.9%.

A synchronization mechanism that enables synchronous operation of PWM Pulse Generators.

A variable operating Clock Prescaler (the division ratio from a Peripheral clock can be selected by
software).

Output selector logic ("High", "Low", PWM pulse and "Hi-Z" signal levels can be selected).
