Freescale Semiconductor

insertion, and separate top and bottom output polarity control. The up-counter value is programmable to

support a continuously variable PWM frequency. Both edge- and center-aligned synchronous pulse width

control (0% to 100% modulation) are 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 PWMs incorporate fault protection

with sufficient output drive capability to directly drive standard opto-isolators. A “smoke-inhibit”,

write-once protection feature for key parameters is also included. The PWM is double-buffered and

includes interrupt control to permit integral reload rates to be programmable from 1 to 16. The PWM

modules provide a reference output to synchronize the Analog-to-Digital Converters.

The 56F802 incorporates two 12-bit Analog-to-Digital Converters (ADCs) with a total of five channels.

A full set of standard programmable peripherals is provided that include a Serial Communications

Interface (SCI), and two Quad Timers. Any of these interfaces can be used as General-Purpose

Input/Outputs (GPIO) if that function is not required. An on-chip relaxation oscillator eliminates the need

for an external crystal.

1.3 State of the Art Development Environment

•

Processor ExpertTM (PE) provides a Rapid Application Design (RAD) tool that combines easy-to-use

component-based software application creation with an expert knowledge system.

•

The Code Warrior Integrated Development Environment is a sophisticated tool for code navigation,

compiling, and debugging. A complete set of evaluation modules (EVMs) and development system cards

will support concurrent engineering. Together, PE, Code Warrior and EVMs create a complete, scalable

tools solution for easy, fast, and efficient development.
