is programmable to support a continuously variable PWM frequency. Edge-aligned and center-aligned synchronous pulse width control (0% to 100% modulation) is supported. The device is capable of controlling most motor types: ACIM (AC Induction Motors); both BDC and BLDC (Brush and Brushless DC motors); SRM and VRM (Switched and Variable Reluctance Motors); and stepper motors. The PWM incorporates fault protection and cycle-by-cycle current limiting with sufficient output drive capability to direct

Signal Pins 2.2 Signal Pins After reset, each pin is configured for its primary function (listed first). In the 56F8122, after reset, each pin must be configured for the desired function. The initialization software will configure each pin for the function listed first for each pin, as shown in Table 2-2. Any alternate functionality must be programmed.
