1.1.3 Peripheral Circuits for 56F803

• Pulse Width Modulator module (PWM) with six PWM outputs, three Current Sense inputs, and three Fault

inputs, fault-tolerant design with dead time insertion, supports both center- and edge- aligned modes,

supports Freescale’s patented dead time distortion correction

• Two 12-bit Analog-to-Digital Converters (ADCs), which support two simultaneous conversions; ADC and

PWM modules can be synchronized

• Quadrature Decoder with four inputs (shares pins with Quad Timer)
