synchronous pulse width control (0% to 100% modulation) is 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 PWM  
incorporates fault protection and cycle-by-cycle current limiting with sufficient output drive capability to  
directly drive standard optoisolators. A “smoke-inhibit”, write-once protection feature for key parameters  
is also included. A patented PWM waveform distortion correction circuit is also provided. Each PWM is  
double-buffered and includes interrupt controls to permit integral reload rates to be programmable from  
1/2 (center-aligned mode only) to 16. The PWM module provides reference outputs to synchronize the  
Analog-to-Digital Converters (ADCs) through Quad Timer C, Channel 2.  
The 56F8323 incorporates one Quadrature Decoder capable of capturing all four transitions on the  
two-phase inputs, permitting generation of a number proportional to actual position. Speed computation  
capabilities accommodate both fast- and slow-moving shafts. An integrated watchdog timer in the  
Quadrature Decoder can be programmed with a time-out value to alarm when no shaft motion is detected.  
Each input is filtered to ensure only true transitions are recorded.  
This controller also provides a full set of standard programmable peripherals that include two Serial  
Communications Interfaces (SCIs), two Serial Peripheral Interfaces (SPIs), two Quad Timers, and  
FlexCAN. Any of these interfaces can be used as General Purpose Input/Outputs (GPIOs) if that function  
is not required. A Flex Controller Area Network (FlexCAN) interface (CAN Version 2.0 B-compliant) and  
an internal interrupt controller are also a part of the 56F8323.

56F8123 Features  
The 56F8123 controller includes 32KB of Program Flash, programmable through the JTAG port, and 8KB  
of Data RAM. A total of 8KB of Boot Flash is incorporated for easy customer inclusion of  
field-programmable software routines that can be used to program the main Program Flash memory area.  
The Program Flash memory can be independently bulk erased or erased in pages; Program Flash page  
erase size is 1KB. The Boot Flash memory can also be either bulk or page erased.  
This controller also provides a full set of standard programmable peripherals that include two Serial  
Communications Interfaces (SCIs), two Serial Peripheral Interfaces (SPIs), and two Quad Timers. Any of  
these interfaces can be used as General Purpose Input/Outputs (GPIOs) if that function is not required. An  
internal interrupt controller is also a part of the 56F8123.  
1.3 Award-Winning Development Environment  
TM  
Processor Expert  
(PE) provides a Rapid Application Design (RAD) tool that combines easy-to-use  
component-based software application creation with an expert knowledge system.  
The CodeWarrior Integrated Development Environment is a sophisticated tool for code navigation,  
compiling, and debugging. A complete set of evaluation modules (EVMs), demonstration board kit and  
development system cards will support concurrent engineering. Together, PE, CodeWarrior and EVMs  
create a complete, scalable tools solution for easy, fast, and efficient development.
