Note: Features in italics are NOT available in the 56F8155 device.

• Pulse Width Modulator module:

— In the 56F8355, 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-aligned

and edge-aligned modes

— In the 56F8155, one Pulse Width Modulator module with six PWM outputs, three Current Sense inputs

and three Fault inputs; fault-tolerant design with dead time insertion; supports both center-aligned 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 through Timer C, channels

2 and 3

• Quadrature Decoder:

— In the 56F8355, two four-input Quadrature Decoders or two additional Quad Timers

— In the 56F8155, one four-input Quadrature Decoder, which works in conjunction with Quad Timer A

• Temperature Sensor can be connected, on the board, to any of the ADC inputs to monitor the on-chip

temperature

• Quad Timer:
