motor controller, programmable GPIOs
Abstract The PCA9629A is a highly integrated design for stepper motor control to
off-load CPU usage and enhanced stepper motor drive control logic with
three pulse width drive formats plus ramp-up and ramp-down features.
The motor drive outputs can program one-phase (wave drive), two-phase,
and half-step drive format logic level outputs for stepper motor control
modes as well as General Purpose Output (GPO) in bypass mode. There
are four additional General Purpose Input/Outputs (GPIOs) — two for
interrupt based motor control on P0 and P1 inputs, and two for general
purpose on P2 and P3.
