Abstract: A motor control apparatus to control a motor external to the motor control apparatus includes a microcontroller unit (MCU). The MCU includes mixed signal motor control circuitry adapted to perform back electromotive force (EMF) motor control in a first mode of operation. The mixed signal motor control circuitry is further adapted to perform field oriented control (FOC) in a second mode of operation.
