Introduction
• The TWR-56F8200 is a standalone
development board that can be used
in conjunction with the Tower System
peripheral boards, including the LV3PH
motor control kit (TWR-MC-LV3PH).
The MC56F82748 comes preloaded with
an application demonstrating the ADC
and a FIR filter application that will sense
heat at the four corners of the module.
Other demo applications and complete
instructions and software on how to
turn a 3-phase BLDC motor using the
LV3PH motor control kit are available
at freescale.com/TWR-56F8200.
• The module features serial communication
over USB, CAN circuits and access to
each pin. The module can be powered
by the Tower System, an external
power supply, the USB jack or a board
connected to the Tower System. The
MC56F82748 is surrounded by easy
access scope probes for each pin of the
device. All signals are also available on
the headers for easy and neat coupling
to your project.
• The Universal Multilink is used with the
JTAG connector to allow user code to
be loaded and debugged. The latest
version of firmware is preloaded into
the JM60 USB controller.

MC56F82748 Features
• 50/100 MHz, 50/100 MIPS 32-bit core for fast control loop execution via
single-cycle math computations and parallel moves
• Fractional arithmetic supported for greater speed with four accumulators
• DMA controller for reduced core intervention when shifting data from peripherals
• High-resolution PWM with 312 picosecond resolution for accurate adjustment of
the control loops
• 2 x 12-bit high-speed ADCs with 2.5 MSPS resolution reduce jitter on current
and voltage reads
• Four analog comparators with integrated 6-bit DACs that can enable emergency
shutdown of the PWMs
• Integrated PGAs to increase the accuracy of ADC conversions on small voltages
and currents
• Intermodule crossbar directly connecting any input and/or output with flexibility
for additional logic functions (AND/OR/XOR/NOR)
• 5 V tolerant I/O for cost-effective board design
• Memory resource protection unit to ease safety certification

Step-by-Step Installation Instructions
In this quick start guide, you will learn how to set up the TWR-56F8200 module
and run the default thermistor and LED application.

Connect
the Jumpers
Ensure the jumpers are connected as
shown in the TWR-56F8200 Jumper
Options table in the next section to
power the board in standalone mode
with the USB cable providing power,
control and communications. All other
jumpers are preinstalled at the factory in
the desired configuration.
21
Run the
Thermistor Demo
Plug the USB cable from your computer into
the TWR-56F8200 module. LEDs E0-E7 will
flash in pairs. With a finger, touch one of the
on-board thermistors (RT1, RT2, RT3, RT4)
placed on each corner of the board. By
touching the thermistor, you will increase its
temperature. The change in temperature is
detected by the DSC and it will update the
LED’s flashing pattern. The thermistors and
the LEDs are related as follows:
Thermistor LEDs
RT1 E0, E1
RT2 E2, E3
RT3 E4, E5
RT4 E6, E7
If you remove a finger from the thermistor,
the LED will return to the default flashing
pattern.

Create
a Project
Install CodeWarrior and run the program.
• From the menu, select “File,” “NEW,”
“Bareboard Project.”
• Assign a project name such as
“ProjDSC” and select “Next.”
• Expand the 56800E (DSC) drop
box, expand 56F827xx, select
“MC56F82748,” then select “Next.”
• Select all of the check boxes on
“Connection to be used.” Select
“Next” twice.
• Select Processor Expert, then select
“Finish.”

Quick Start Guide
Build an
Application
Wait for Processor Expert to finish loading.
Activity progress can be seen in the lower
right of the IDE screen.
Once idle, click on the project name
“ProjDSC” and then select the hammer
icon to build the project.

Debug an
Application
Set a breakpoint at the “for” instruction
from within the C language program by
right-clicking in the margin to the left of
the “for” statement and selecting “toggle
breakpoint ” from the drop-down list.
From the menu bar at the top of the screen,
find and press the green “play/resume”
button or use F8 on your keyboard.
Quick Start Guide
Load an Application
using Universal Multilink
Connect the Universal Multilink to the
JTAG Connector J14. Make sure the
red wire of the Universal Multilink ribbon
cable connects to pin1 of J14 and
connect the other end to your PC. When
finished building, right-click on the project
name. Select “debug as,” “CodeWarrior
Download.” Select “PnE U-MultiLink” and
click “OK.”
Activity progress can be seen in the
lower portion of the IDE screen. Once
the debugger runs, it will stop in the main
program, allowing you to take control.

Resume Your Application
at a Breakpoint
The code will run up to the breakpoint
that you set in the previous step. When
it reaches it, the code will stop in the
debugger and display the current
location from which the code is running
at your breakpoint. You then can resume
execution or examine elements of the
application in the IDE.
Run a Sample
Project
Find a desired application in the
“MC56F827xx CodeExample” directory or
develop your own project.
For project importing, exporting and
running directions, see the Getting
Started section of the TWR-56F8200
User Manual, available for download at
freescale.com/TWR-56F8200.
Run 3-Phase BLDC
Motor with LV3PH Motor
Control Kit
To run the 3-phase low-voltage BLDC
motor using the MCLV TWR card, refer to
the “Getting Started” chapter of the TWR-
56F8200 User Manual.
Further Instruction for
TWR-MC-LV3PH Motor
To get a TWR-MC-LV3PH motor turning
quickly, refer to the “Getting Started”
chapter of the TWR-56F8200 User
Manual. Here you will find instructions
detailing how to program your TWR card
with the Motor Spin demo. The software
demonstrates how to get the motor
spinning and then control the motor speed
and direction via the FreeMaster Graphical
User Interface. For more information
