ABSTRACT
This document describes how to get the LP5523 evaluation board up and running, how to use evaluation
and programming software, and how to get started with programming.
Getting Started with LP5523
The application note is divided into four separate sections: The first section, General Description, provides
general information for getting started with the LP5523 evaluation hardware and software. The second
section, LP5523 Programming, shows LP5523 programming flow. The third section, Instruction Set
Details, gives a detailed description of the device’s instruction set. Finally, the fourth section, Programming
Examples, gives practical programming examples.
General Description
The LP5523 provides flexibility and programmability for dimming and sequencing control. Each LED can
be controlled directly and independently through the serial bus (in other words, without programming the
engines), or LED drivers can be controlled by programming the execution engines. The LP5523 has three
independent program execution engines, so it is possible to form three independently programmable LED
banks. LED drivers can be grouped based on their function so that, for example, the first bank of drivers
can be assigned to the keypad illumination, the second bank to the “funlights” and the third group to the
indicator LED(s). Each bank can contain 1 to 9 LED driver outputs. Instructions for program execution
engines are stored in the internal program memory. The total amount of the program memory is 96
instructions and the user can allocate the memory as required by the engines. The LP5523 is
programmed using a I2C-compatible serial bus. Of course, it is possible to write programs for the LP5523
in the form of binary data, but the programming tools described in this document offers a more convenient
way to write (and read) the registers and the SRAM memory and to program the device.
WHAT IS NEEDED
To

get started you will need:
A text editor
LP5523 evaluation kit hardware
LP5523 evaluation software (LP5523.exe)
LP5523 compiler (LASM.EXE)
FTDI virtual com port drivers (VCP)
A text editor is used to create source code for the assembler. Here, we use PSPAd as a text editor, but
you should feel free to use whatever editor you are most comfortable with. PSPad is a freeware editor, ©
1991 - 2007 Jan Fiala. Please see the PSPad copyright notice. PSPad text editor can be downloaded
from http://www.pspad.com/
INSTALLING FTDI DRIVERS
The evaluation board has FTDI's FT232R USB to UART chip on it. FT232R allows the PC to see the
evaluation board as a virtual COM port. For this FTDI VCP drivers must be installed to the host computer.
Usually Windows can install the drivers automatically when the evaluation board is detected. If Windows
fails to instal the drivers, they can be downloaded from www.ftdichip.com. Make sure that you download
and instal VCP drivers and not the D2XX drivers.

Once FTDI drivers are installed and evaluation board is plugged in to USB port Windows generates an
USB serial port. This port is given unique COM port number. Note that the evaluation program polls only
the first 8 COM ports. If the evaluation program does not find the evaluation board you may need to
change the COM port number manually. In Windows go to the Control Panel, select System, select
Hardware tab, open Device Manager, select Ports and you should see the USB SerialPort number. If the
port number is above 8 you will need to change it. Right clicking the USB Serial Port, selecting Properties,
select Port Settings, click Advanced button and select COM port number between 1 to 8.
COPYING THE SOFTWARE
PSPad does not require installation, it can be simply unpacked into any directory. The archive contains
subdirectories and must be unpacked with subdirectory preservation enabled. Also copy the Lysti.ini –file
into the Syntax-folder of PSPad (for example C:\Program Files\PSPad editor\Syntax). Lysti.ini –file
contains customization information for the text editor and it must be saved into the Syntax-folder.
LP5523 assembler (LASM.exe) and LP5523 evaluation software can be copied to the PC’s hard disk and
run without installation. You will need to copy the following files: LP5523.exe, regmap.ini, usblptio.dll,
rtl60.bpl and LASM.exe. All the files must lie in the same directory. Also the source code files which you
will create (*.scr) should be saved/placed in the same directory as the LASM.exe before calling the
assembler. Please avoid filenames or directory names containing a space character, since the assembler
may fail when applied to filenames containing a space character. The evaluation software runs under
Windows 2000/XP/Vista.
PSPAD CUSTOMIZATION
Once you run the PSPad editor, you should customize the editor for LP5523 as follows:
1. Select Settings menu > Highlighter settings.
2. Select Specification tab. See PSPad Highlighter Specification Settings for LP5523.
3. On the left (highlighter) list, click on one of bolded highlighters (marked with -tab).
4. On the right side is list of user highlighters, select the Lysti highlighter and click on it (see PSPad
Highlighter Specification Settings for LP5523). Click on ‘Apply’ to confirm this action.
Also set the compiler search path and parameters for the LASM.exe, as shown in PSPad compiler
settings for LP5523. You may need to replace the shown filepath C:\data\LP5523\LASM\LASM.exe with
your actual path. Tag the Capture Program Output Window as shown in PSPad compiler settings for
LP5523. Accept highlighter settings by clicking ‘OK’. Finally, in the main window show the LOG window by
pressing CTRL + L. All software needed should be now ready for writing and assembling the first program.
Note: The maximum length of a source code line is 140 characters. Lines that are longer than 140 are not
assembled correctly.

HARDWARE SET-UP
LP5523 Evaluation Board
The LP5523 evaluation board has USB communication and evaluation related components assembled
onto one board. (See LP5523 Evaluation Board). The evaluation board was designed specially for
evaluation and therefore is not optimized for the smallest layout size. The components are physically large
to make changing of the value easy if needed. The LP5523 input voltage VDD is supplied from the USB
port or from an external voltage applied to the X4 connector.

LP5523 Evaluation Board (continued)
There are 7 pin connectors (jumpers) on the evaluation board for demonstrating some of the possible
application options (see LP5523 Evaluation Board). The voltage supplied to the VDD input of the device
can be selected using J2 connector. Connecting right and center pin with jumper selects that VDD is fed
from USB and connecting left and center pin with jumper selects that VDD is fed from connector X4. Also
whether VDDIO is powered from USB or from external voltage supply (X3 connector) can be selected with
J1. Connecting right and center pin with jumper selects that VDDIO is fed from USB and connecting left and
center pin with jumper selects that VDDIO is fed from connector X3. Voltage on the USB port is 5.0V and
the maximum current is 500 mA. There is a voltage regulator on the evaluation board which reduces the
USB bus voltage to 3.3V. Connector X4 upper connection point is for VDD and lower for Ground.
Connector X3 upper connection point is for VDDIO and lower for Ground.
Pin connectors J10 J11, J12 are for selecting whether LP5523 LED outputs are connected to WLEDs or
RGBs. If lower and center pins are connected with jumper, J10 connects output 1 to D1 green, output 2 to
D1 blue and output 7 to D1 red. If upper and center pins are connected with jumper output 1 is connected
to D4, output 2 to D5 and output 3 to D6. Pin connector J11 connects outputs 3 to D2 green, output 4 to
D2 blue and output 8 to D2 red if lower and center pins connected with jumper. If upper and center pins
are connected with jumper output 4 is connected to D7, output 5 to D8 and output 6 to D9. Pin connector
J12 connects output 5 to D3 green, output 6 to D3 blue and output 9 D3 red if lower and center pins
connected with jumper. If higher and center pins are connected with jumper output 5 is connected to D10,
output 8 to D11 and output 9 to D12. It is recommended that either RGB or white LEDs are used and not
mixed.
Pin connectors J13 and J14 are used to connect on board light sensor to LP5523. If J14 connectors left
and center pins are connected with jumper light sensors output is connected to INT pin. If J14 connectors
right and center pins are connected with jumper INT pin is connected to D14 LED. If J13 connectors left
and center pins are connected with jumper light sensors GC1 pin is connected to LP5523 GPO pin. In this
case pulling GPO sets the light sensor into standby mode. If this function is not desired J13 can be left
open. Light sensor's GC1 pin is pulled high with R10. Jumper Options summarizes the available options.

software. LP5523 Evaluation Software Control Panel shows the evaluation software user interface
(Control Panel).
You should see USB OK message on the status bar (shown in the lower part of the window). If the USB
communication is not working correctly, shut down the evaluation software and unplug the USB cable.
Plug in the USB cable again and reset the evaluation board by pressing the on board reset button (S1).
Wait about 5 seconds and repeat steps 4 to 6 above. If evaluation software is still unable to find evaluation
board you'll need to change com port settings as described in chapter INSTALLING FTDI DRIVERS.
CONTROLLING EVALUATION BOARD FROM PC
The evaluation software provides read-write control over the registers within the LP5523. Bits can be set
from a logical ‘1’ to a logical ‘0’ or vice versa by a mouse click and for some settings there is also a slider
control provided. The evaluation software window is divided into two panels: control panel and indicator
panel (see LP5523 Evaluation Software Control Panel). The leftmost panel is the indicator panel and it
shows the status of the LP5523 registers (excluding the program memory).

The rightmost panel is the control panel and it is used to change the status of the registers, to program the
device, or to debug the program depending on the selected view. The view is selected by the tabs on the
top of the window. The Manual view appears when the evaluation software starts. The Manual view is
used to run the device "manually"; for example, the program execution engines are not used. It contains
also some LP5523 basic settings, like serial bus address selection. In the next chapter the user is guided
through the Manual view and basic operations of the LP5523. The other views are Program, Code
memory and History; these views are presented in the chapter 2 covering programming of the LP5523.
Tip: The context-sensitive buttons in the lower part of the window can be used for direct Write/Read
operations of the registers. The target register is indicated by red cross and the target can be changed by
clicking on the desired register on the indicator panel.
DIRECT CONTROL
Enabling the Device and Starting the Charge Pump
The first step to start with the LP5523 is to enable the chip; tag the Chip enabled check box. At first it is
best to use the following settings: Clock internal and Charge pump gain 1.5x (see LP5523 Evaluation
Software Control Panel). At this point it is good to ensure the charge pump output voltage with the LP5523
built-in LED error detection. To do this, select VOUT from the LED test drop down menu and tag Start
conversion. Use the adjacent RD button to read the result: it should be around 4.5 volts. Also click on the
RD button on the Status/Interrupt section to verify that the internal clock is used (Ext clk indicator light
should be OFF) and that the LED test is done (LED test done indicator should be ON).
Setting the Led Current and PWM
The next step is to set the desired LED currents. This is done by Current slider. Set 5 mA current for
LED1 and set PWM to 50% = 7Fhex. You should have a green LED switched on now. Note: When the
Update immediately tag is set, the evaluation software will write the new settings immediately to the
LP5523 registers. Otherwise you need to click on the Update button.
The basic idea behind LP5523 operation is to first set the LED currents to the required level and after that
the current settings are not touched any more – all the fade-in and fade-out sections (ramps) and the
temperature compensation is done by PWM . Each LED has its own constant current output and all the
outputs can be controlled independently. Therefore LED pre-selection (matched LEDs) is not required and
this kind of architecture supports also color control. The PWM, current and temperature compensation
controls are organised under tabs labelled by LED1 to LED 9. Now, let’s set 5 mA current and 50% PWM
for LED2 and 3,5mA current and 50% PWM for LED7. As a result, D1 on evaluation board should emit
white light.
Master Fader
The PWM of LED driver outputs can be controlled individually as as described above, or alternatively the
drivers can be grouped by function to provide a quick control. The LP5523 has three master fader
registers, so it is possible to form three master fader groups. To assign an LED to a group, use the Master
Fader drop down menu. Select Group 1 for LEDs 1, 2, and 7. Now you can control all the three outputs
with a single master fader register. There is a Master fader slider provided on the right side of the control
panel and dragging the slider under tab labelled by 1 controls now LEDs 1, 2, and 7. Note that the initial
PWM and current for LEDs in a group needs to be set before using the master fader control, since master
fader is simply a multiplier, which acts on the PWM registers.
Logarithmic vs Linear PWM Response
Logarithmic response is used to give the impression of a linear light intensity increase/decrease as the
PWM duty cycle is raised/reduced. Logarithmic response is visually more pleasing especially when the
overall brightness is low. To activate the logarithmic response, tag logarithmic adjustment. Activate
logarithmic adjustment for LEDs 1, 2 and 7. Set also 5 mA current for LEDs 3 and 4, set 3.5mA for LED8.
Set 50% PWM for LEDs 3, 4 and 8. Assign LEDs 3, 4 and 8 to the master fader group 1 so that you can
control all the six LEDs with one slider. Now you should have logarithmic control over the LEDs 1, 2, 7
and linear control over the LEDs 3, 4, 8. To see the difference between the lin and log response, move the
slider backwards and forwards to alter the intensity of all the six LEDs at once.

Temperature Compensation
The LP5523 has a temperature compensation function to correct for variations in light intensity and color
caused by changes in ambient temperature.
Reset the LP5523 and start the charge pump as shown in LP5523 Evaluation Software Control Panel. Set
5 mA current, 50% PWM for LEDs 1 and 2; Set 3,5 mA current, 50 % PWM for LED 7.
In order to activate the compensation function tag the check box next to Correction factor slider. The slope
for the temperature compensation line can be set by the slider. A simple approximation for the RGB LED
temperature compensation would be +1.3%/°C for red LED and +0.2%/°C for green and blue so that the
intensity of all the colors remain approximately the same over the temperature from 25°C to 60°C .
To observe the effect of the compensation on color, try the following: Under Temperature label, tag Start
conversion (this enables the LP5523 internal temperature sensor) and continuous measurement
(continuous temperature measurement). Enter 25°C to the External sensor box and click on WR button to
write the reading to the LP5523 memory. Now toggle between internal sensor and external sensor as you
warm up the LEDs and LP5523 with a hair dryer. When the “external sensor” is active, the temperature
information is read from register TEMPERATURE WRITE (addr. 40H). When the temperature is 25°C all
the compensation settings have no effect, so when you have the external sensor activated, you will see
the “uncompensated” situation. When you activate the internal sensor, you will see the effect of the
compensation as the ambient temperature is raised. Without compensation emitted light will be drifted
somewhat towards a more bluish white, because the red LED element of the RGB LED shows the
strongest temperature dependence.
LED Error Detection
To measure VF of an LED set PWM = 100% for the LED and set the desired LED current with the current
slider. Disable temperature compensation. On LED test portion tag Start conversion and Continuous
measurement. Click on RD button to read the test result from LP5523’s internal register. Try with different
current settings and compare the result with the value specified by the manufacturer. If there is a short to
ground in the LED circuit the result is ~0V and if there is an open the result is ~4,5V. This feature can also
be addressed to measure the voltage on VDD, VOUT and INT pins. Typical example usage includes
monitoring battery voltage or using INT pin as a light sensor interface (A/D converter value can be used as
a variable in program control).
Charge Pump Gain Control
Charge pump gain can be forced to 1x, 1.5x, or you can let the LP5523 decide the best charge pump gain
based on LED forward voltage requirements by selecting AUTO mode (this is the most useful setting in
real applications). Note that outputs D7, D8, and D9 are powered directly from VDD and they have no
effect on gain change decision-making. LP5523 charge pump has a gain change hysteresis which
prevents the mode from toggling back and forth (1x -> 1.5x -> 1x...), which would cause ripple on VIN and
LED flicker.
The hysteresis region width depends on the choice of threshold voltage. Threshold voltage is defined as
follows VTHRESHOLD = VDD - MAX(voltage on D1 to D6). If VTHRESHOLD is larger than the set value
(100mV to 400mV), the charge pump is in 1x mode. A good compromise solution between efficiency and
performance is 200mV. In addition to take the charge pump total load current into account enable the
adaptive hysteresis.
Timer enable activates forced mode change. In forced mode charge pump mode change from 1.5x to 1x is
attempted at the constant interval specified by the Timer control. With infinite setting the charge pump
switches gain from 1x mode to 1.5x mode only. The gain reset back to 1x is enabled under certain
conditions, for example in the powersave mode. Forced mode and treshold parameters are used to
optimize efficiency in a real design - it is desired that 1.5x gain is used only when needed.
LP5523 Programming
PROGRAMMING FLOW CHART
Programming Flow Chart shows the typical programming flow of the LP5523. The program is first typed in
with PSPad (or equivalent) text editor. Then the program is compiled into a hex and binary file. Finally the
hex file is loaded into the LP5523's memory and tested.

THE STRUCTURE OF A LP5523 PROGRAM
Example Code of LP5523 Programshows an example of a LP5523 program. When this program is run,
the program will flash a red LED once per second.
Although this program is short and simple it shows all the main parts of a typical LP5523 program.
Commenting
Commenting starts with a semicolon (;). The compiler will ignore all characters after a semicolon. If you
are using PSPad editor and you have customized the editor according to the instructions on first pages of
this document, the editor recognizes comments, directives, labels and instructions automatically and uses
different highlighter colors for different datatypes.
Directives
The directives are not translated directly into LP5523. Instead, directives are instructions for the LASM.exe
compiler. Directives are used to adjust the location of the engine 1, 2 and 3 programs in memory and
reserve memory resources in the LP5523 SRAM. For example .segment program1 is a directive which
tells to the compiler that whatever follows is the program for the program execution engine 1. An overview
of the directives is given in the following table.
Directive
Description
.segment
Adjust the location of the programs in SRAM. Note the leading dot .segment program1
.segment flashing_light
Example source code
ds
Define Storage; The directive reserves memory resources in the
SRAM. The ds directive takes one parameter, which is the
number of words to reserve. The number of bits in a word (word
length) is 16. The allocated words are initialized with zeros
ds 3
ds 17
dw
Define constant Word. Inserts a binary word to the SRAM.
dw 0000000011111111b
dw FFABh
dw 3
Labels
A label is a symbolic address. Labels are used to mark program line(s), like in branch instruction and
labeling mapping table rows. Labels must have the colon (:) suffix. In the Example Code of LP5523
Program code loop1: is a label which indicates the starting address of the loop.

Instructions
Instructions are executable statements. LASM-compiler translates text-based language source instructions
into hex- and binary-based executable codes. In the example code presented in Example Code of LP5523
Program for example set_pwm is an instruction. Almost all the instructions take operands, which may be
constants (like FFh), or variables stored in the LP5523 registers (like ra) - ra stands for variable a (register
a), rb, for variable b, etc.
Example Code of LP5523 Program
PRODUCING AN EXECUTABLE FILE
Once the text-based source file is typed in and saved using the text editor (PSPad), the source code
window should look like the one in Example of Compiling Source Code. To call the compiler routine, select
File >> Compile. The PSPad LOG window shows the progress of compiling. If the compiler generates
error messages, LOG window is necessary for locating these errors.
A listing file, a hex file and a binary file is produced by the LASM.exe compiler. The name of the files are
the same name that you have given to the source code file, with the *.lst, *.hex or *.bin extension. *.hex
and *.bin files contain the machine code.

Example of Compiling Source Code
LOADING A PROGRAM TO THE LP5523'S SRAM
To upload code into the LP5523 SRAM start the LP5523.exe evaluation software. Select the Program tab
Master Control of the Program Tab. The Program tab is divided into two parts: the right contains the
program's source code and the compiled version of the code; the left part contains program execution
engine controls. Load the generated *.hex file into the evaluation software view: Click Open Source File
button ( Open Source File Button In Program Tab), browse the file and click Open.
Open Source File Button In Program Tab
To download the machine code into the LP5523, click on download button Download Opened Source File
Into LP5523. Pressing this button sets all the engine modes to Load.
Download Opened Source File Into LP5523
Program can be loaded also from the Code memory tab Code Memory Tab. In this case one must set the
operation mode to Load. In Code memory tab one must first select the address where data is written.
Once the address is active Data can be written in hexadecimal to the Data entry field and push the Update
button. Once all the data is updated to the wanted addresses, it can be written to the SRAM memory by
pushing the Write Page, which writes two lines in code memory table (first two lines refer to page 0, next
two lines to page 1, etc. Pages can be changed with the page selector) or by pushing Write All, which
updates the whole memory. Once the data is written to SRAM, operation mode can be set to Run and
Execution mode for example to Free Run. Note that Program Counter(s) must be set accordingly. This is
not done automatically like loading program by clicking the Download-button. Note also that the program
code does not show up in the program view (in Program tab).

RUNNING THE PROGRAM
The program is run by checking the Run from the Master control and clicking on Free run-button. This way
all the engines will start at the same time. If you have less than three engines in use, extra engines must
be disabled by checking off the box in each engine section. Like in Master Control of the Program Tab
program has only two engines in use and the engine three is checked off. If this is not done the programs
may not work correctly. Engines can also be run from individual engine control. One convenient way of
debugging the programs is by running the individual engines step by step. Individual engine control can be
used also with multiple engines, but then they wont start at the same time.
Master Control of the Program Tab
For operating the programs following four modes exist (see Master Control of the Program Tab).
Operation mode is selected by clicking the desired check box.
Operation modes
• Disable — Engine operation is disabled and they can not be run
• Load — In this mode writing to program memory is allowed. All the three engines are in hold while one
or more engines are in load program mode. PWM values are also frozen. Program execution continues
when all the engines are out of load program mode. Load program mode resets the program counter of
the respective engine. Load program mode can be entered from the disabled mode only. Entering load
program mode from the run program mode is not allowed. Note that load mode does not automatically
load the program opened with Open Source File button Open Source File Button In Program Tab.
When using this operation mode, one must write the program through the Code memory tab .
• Run — This mode executes the instructions stored in the program memory. Execution register
(ENG1_EXEC etc.) bits define how the program is executed (hold, step, free run or execute once).
Program start address can be programmed to Program Counter (PC) register. The Program Counter is
reset to zero when the PC’s upper limit value is reached.
• Halt — In this mode instruction execution aborts immediately and engine operation halts. Execution
can be continued if operation mode is set to Run again.
For executing the programs following four modes exist. Execution mode is selected with the four push
buttons. Functions of the buttons from left to right are:

Master Control of the Program Tab (continued)
•

•
•
Stop — Engine execution is stopped. The current instruction is executed and then execution stopped.
Step — Execute the instruction at the location pointed by the Program Counter, increment the
Program Counter by one and then reset ENG1_EXEC bits to 00 (enter Stop-mode).
Execute Command — Execute the instruction pointed by the current Program Counter value and
reset ENG1_EXEC to 00 (for example, enter Stop-mode). The difference between Step and Execute
Command is that Execute Command does not increment the Program Counter.
Free Run — Start program execution from the instruction pointed by the Program Counter.
Code Memory Tab
DEBUGGING CONSIDERATIONS
There are a few ways to see how the compiler translates the instructions to machine code. Listing file
(*.lst) may be used for locating assembling errors. The listing file contains the source code along with the
compiled machine code. You can examine the files in any text editor. This is helpful for debugging and
seeing how source code is translated into machine code. Listing File of the Example Program First shows
an example of listing file. The first column is the row number, second column indicates the SRAM memory
address, third shows the machine code data and fourth column includes the source code. Note that the
.segment directives show the start address of the program, for example, where to the Program Counters
should point.
From the produced two hex-files user can see the pure machine code represented in hexadecimal in two
different ways. In *.he2 —file representation of data is 0xYY (YY being the changing data information). In
*.hex file the data is represented YY, where YY is the changing data information. In *.he2 file the 8–bit
long data elements are separated with comma whereas in *.hex file they are separated with tab. In both
files data is represented like in Code memory tab memory table. First two columns correspond to first
column in Code memory tab memory table, third and fourth columns correspond to second column etc.

For example if the user would have mux_inc instruction (9D80), in he2 it would be 0x9D, 0x80 and in hex
file it would be 9D [tab] 80. In hex-file the start addresses of the programs are at the bottom whereas in
*.he2 file they are on the first row engine 1 start address being first, engine 2 second and engine 3 start
address third. Also in the bin-file user can see the pure machine code represented in binary. First three
rows represent the start addresses of the programs. After the start addresses the program code follows.
Programs can be debugged in the evaluation software Program tab by running the program in steps using
Step or Execute command execution modes. Also one way to see what is written to the LP5523 is to look
at the evaluation program History tab History Tab.

Programming Examples
This section gives practical programming examples. A series of programs introduce the main features of
the LP5523 chip and the example programs are easy to tailor to the specific needs of end application.
EXAMPLE 1: CONTROLLING MULTIPLE LEDS WITH ONE ENGINE
The example below is basically the program shown in the Example Code of LP5523 Program before
(simple LP5523 program), but here so called mapping table is used to establish engine1-to-LEDs
connection. In the mapping table '0' means that the LED isn't connected to the engine; '1' means that the
LED is connected to the engine. In the example program below bits 6 to 8 are set to ‘1’ so that outputs 7,
8 and 9 are mapped to the engine 1.

EXAMPLE 2: FADE-IN/FADEOUT EFFECTS AND CHANGING MAPPING OF LEDS
In this example ramp instruction is used to produce fade-in/fade-out effects. Note: The use of a logarithmic
PWM profile with ramp instruction ensures the light and color changes appear smooth to the human eye.
The same effect is repeated for all the LEDs by changing the engine1-to-LED mapping. After that, the
intensity of the LEDs is increased gradually and finally all the LEDs are set OFF.

EXAMPLE 4: TRIGGERS AND INTERRUPT
This program shows how to use triggers and the interrupt. Engine 1 sends a trigger to Engine 2 when it
has set a LED to 100% PWM – Engine 2 fades the LED out to 0% PWM. Engine 1 sends an interrupt
when it has finished loop1 and waits trigger from Engine 2 AND an external trigger. Pushing the button on
the evaluation board causes an external trigger and the sequence starts over. Use RD button on the
Status/Interrupt section (see Programming Flow Chart) to clear the interrupt.
