10. On-Board debugging

Before using the On-Board debug function of the EB-V850ES/HG2-EE board together with the IAR C-SPY
debugger i t is necessary to install the USB driver f irst. The EB-V850ES/HG2-EE starterkit uses a monitor
program for debugging purpose. The communication between the starterkit and the IAR C-SPY debugger ­that is running on the personal computer - is done via the standard UART / USB connection. The monitor
program is automatically downloaded to the starterkit in that case when the V850ES/HG2 internal FLASH
memory was erased by the user i.e. by using the FPL. Therefore the user has not to take care about the
monitor.

For communication interface the build-in UARTA0 of the V850ES/HG2 device is used by the monitor.
Consequently it can not be used by the user application.

To set the EB-V850ES/HG2-EE starterkit to the On-Board debug mode configure SW3 as following:

SW3 Configuration

Bit 1 ON
Bit 2 ON
Bit 3 ON
Bit 4 OFF

66

EB-V850ES/HG2-EE

10.1 Monitor resources

The debugging feature of the EB-V850ES/HG2-EE starterkit has been realized by a monitor program that is
running on the V850ES/HG2 device. Therefore, the following resources are reserved by monitor and can
not be used by a user program.

10.1.1 UARTA0

The UARTA0 of the V850ES/HG2 device is reserved for the monitor program and can not be used by a user
program.

Device UART for

Debugging

V850ES/HG2
(µPD70F3707)

Additionally, please note the following points:

• Do not change the control registers of UARTA0.

• Do not change or disable the interrupt control / mask flags of UARTA0.

• Do not change the port mode or port mode control registers for port bits P30 and P31.

• Debugging functions like forcible break (debugger stop command) do not operate normally in the

following states where the clock supply to UARTA0 is disabled:

 IDLE mode
 STOP mode
 Main oscillation (fx) is stopped.

UARTA0 UA0RMK P30 / TXDA0

Interrupt

Terminal used

P31 / RXDA0

10.1.2 Interrupt vectors

The following interrupt vectors are used by the monitor program and can not be used by a user program.

Device Interrupt vector

0x0270 – 0x0273 UARTA0 receive interrupt vector

Function

67

EB-V850ES/HG2-EE

10.1.3 Reset vector

When a user program is downloaded by using the IAR C-SPY debugger, the reset vector (address 0x0000)
of the user program is replaced by the one of monitor program. The debugger moves the reset vector of the
user program automatically to address 0x0004. The correction of the relative jump address is also done
automatically by the debugger.

Example:

0x0000
0x0006
0x0008

10.1.4 Memory area

The monitor program is located in the highest FLASH block of the V850ES/HG2 device. Only 2 kByte of
memory are allocated by the monitor program.

Device Address range Function

V850ES/HG2
(µPD70F3707)

Moreover, the monitor reserves 36 bytes of the global stack area by halting the user program, caused by a
forcible break (debugger stop c omm and) or a software breakpoint.

10.1.5 Clock operation

After releasing a reset, the monitor program sets the operation clock of the CPU to the maximum speed of
20 MHz. The monitor program switches also to the maximum CPU speed of 20 MHz when releasing a
forcible break (debugger stop command) or when the user program execution is stopped caused by a
software breakpoint. After the user program execution is restarted (debugger go command) the monitor
restores the previous CPU operation clock setting.

Note: Do not change the frequency of the external oscillator connected to the X1 and X2 pins.

10.1.6 Other limitations

The watchdog timer 1 and 2 can not be used. Please be sure to set the option bytes of the V850ES/HG2
device accordingly to allow the watchdog timer disable.

The forcible break (debugger st op command) can not be used when the global interrupts were disabled by
the user program (DI instruction).

11. Sample programs

11.1 General Introduction

Each of the sample programs is located in a single directory, which will be called main-directory of the
sample. This main directory of each sample contains the complete project inclusive all output files of the
development tool. The workspace file “EB_V850ESHG2_EE.eww” is located on top of the sample program
directories. All sample programs use the same directory structure:

Count Down Timer

Debug
inc
Release
settings
source
xcl

CountDownTimer.dep
CountDownTimer.ewd
CountDownTimer.ewp

Electronic Dice
Entrance Code Checker
Lightshow
Melody Maker
Reaction Time Measurement

EB_V850ESHG2_EE.eww

Table 18: Example directory structure

The main directory contains only the project files for the IAR Systems Embedded Workbench. All source
files are located in the directory /source and th e /inc directory contains the header files. The /xcl
directory contains the linker control file of the V850ES/HG2 device. Each sample project uses two targets.
One target is the “Debug” (directory /Debug) that holds all information for debugging purpose and the other
one the “Release” target (directory /Release) contains the programmable file, i.e. the Intel HEX file, for
prog ramming the V850ES/HG2 internal FLASH memory by using the FPL soft ware.

All output files of the development tools for the corresponding target are generated in the directories
/Debug and /Release.

For details of using the IAR Embedded Workbench and the IAR C-SPY debugger please refer to the “V850
IAR Embedded Workbench IDE User Guide”.

11.2 Count Down Timer

With this sample program the board can be used as a count down timer. After the signal for program start
the program waits for the input of the counter time, which can be set by key SW2. Each key press increases
the time by 60 seconds. The current time is shown by the 7 segment LED in units of minutes. A press of
button SW1 starts the timer, which is shown by the flashing dot of the 7 segment LED.
After the selected time is finished, the 7 segment LED flashes for 3 minutes. Then the program goes to
stand by modus. A key press during countdown time or st and-by-modus s ets the program to input mode
again.

Timer P1 is working in the modus ‘clear and start on match between Timer P1 (TMP1) and TP1CCR0’.
According to the selected operating frequency and the value of the compare register TP1CCR0 Timer P1

11.3 Electronic Dice

This sample program simulates a dice. After the program-start-signal, the program waits for a press of
button SW1. After an animation of a rolling dice a random number between one and six is generated and
shown on the 7 segment LED.

The ‘random’ number is generated by a transformation of the timer value of Timer P2 to a number between
one and six. Timer P2 is working at 2.5 MHz using a compare value of 80 in the modus ‘clear and start on
match between TMP2 and TP2CCR0’. The result is an interrupt repetition time of 31,25 KHz. The Timer P1
is working in the same modus to generate a 25ms timebase.

11.4 Entrance c ode checker

This sample program waits for a sequence of five keystrokes. If the input sequence matches the predefined
sequence, the 7 segment LED displays “O” and the port P4.1 is switched ON for 5 seconds. Otherwise, the
7 segment LED flashes “F” five times. Then the program waits for a new input sequence. The code
sequence is stored in the array ucCode. The default sequence is Button SW1 - Button SW1 – Button SW2 ­Button SW1 – Button SW1. During input of the entrance code the 7 segment LED shows the accepted key
press.

The Timer P1 (TMP1) is working in the modus ‘clear and start on match between TMP1 and TP1CCR0’.
According to the selected operating frequency and the value of the compare register TP1CCR0, a 25ms

11.7 R e ac ti on t i m e me a su r em e n t

This sample program demonstrates a reaction time measurement. After a press of button SW1 the
application waits for a random time between 0.50 and 3.45 seconds. Then the 7 segment LED is switched
on and measurement starts. Until the next keystrokes of button SW1 every 50 ms the counter value is
incremented and the actual count value is displayed by the 7 segment LED. Pressing button SW2 starts a
new measuring cycle.
Timer P3 is working at 2.5 MHz using a compar e value of 80 in the modus ‘clear and start on match
