1.1.3 Peripheral Circuits for 56F807

• Two Pulse Width Modulator modules each with six PWM outputs, three Current Sense inputs, and

four Fault inputs, fault tolerant design with dead time insertion, supports both center- and

edge-aligned modes

• Four 12-bit, Analog-to-Digital Converters (ADCs), which support four simultaneous conversions

with quad, 4-pin multiplexed inputs; ADC and PWM modules can be synchronized
