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 and cycle-by-

cycle current limiting 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 56F801 incorporates an 8 input, 12-bit Analog-to-Digital Converter (ADC). A full set of standard

programmable peripherals is provided that include a Serial Communications Interface (SCI), a Serial

Peripheral Interface (SPI), 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 provides flexibility

in the choice of either on-chip or externally supplied frequency reference for chip timing operations.

Application code is used to select which source is to be used.

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.
