3.4 Functional Description of Each Part
3.4.1 ICD board
The ICD board is a hardware tool (emulator) to facilitate the development of software for the S1C17702. It controls
communication between your PC and the target IC (S1C17702) on the CPU board, providing a simple software
development environment for S1C17702. For information about its functional differences from the ICD Mini
(S5U1C17001H), a development tool supporting all S1C17 core product models, see Chapter 6.
ICD Board Reset Switch
Pressing the reset switch (SW1) on the ICD board reboots firmware on the ICD board and outputs the target
reset signal (#RESET_OUT) to the CPU board. This establishes the communication connection between the
CPU board and the ICD board if they are physically connected. If the CPU board and the ICD board are not
connected physically, the ICD board waits for a connection for communication.
ICD Board LED
The LED indicates ICD board and target statuses in different colors.
● (Blue) Power on (before the initial connection with the target is established.)
●
(Green) The target is currently in debug mode.
●(Red) The target is not connected, or not properly connected.
The target is currently executing a user program.
3.4.2 CPU board
The CPU board is a simple target evaluation board equipped with the target CPU (S1C17702). It also contains various peripheral functions and circuits, such as LCD panel and remote control transmitter/receiver module. It can be
used to develop and evaluate software for controlling these components.
CPU Board Reset Switch
Pressing the CPU board reset switch (SW5) resets the CPU board.
Coin cell battery
A holder for the coin cell battery (CR2032) is mounted on the back side of the CPU board. If the CPU board is
used alone, power is supplied from the coin cell battery.If the SVT17702 is used with the ICD board connected,
the switch circuit on the CPU board automatically supply power to the SV17702 from the ICD board.Power
supply from the coin cell battery is then automatically turned off.

5 Operating Environment and Start-Up
Procedures
By connecting with your PC via the ICD board, the SVT17702 can be operated in accordance with commands executed from a debugger on the PC. The SVT17801 is capable of operating the CPU board alone without using the
ICD board and PC. The following sections describe the connection and startup procedures to perform each respective operation.
5.1 Simple Software Development Environments
The SVT17702 provides a simple development environment of S1C17702 software using the CPU board as a target. This can be achieved by connecting the SVT17202 to your PC via the ICD board and using it with an S1C17
development tool on the PC (such as GNU17 IDE, compiler and debugger included in the S5U1C17001C package).
Figure 5.1.1 Simple Software Development Environment
Operations under simple software development environment
Under this operating environment,the target CPU (the S1C17702 on the CPU board) operates according to
commands executed from a debugger on your PC connected with the ICD board.A command executed from the
debugger is sent to the ICD board via USB and, when it has been analyzed, converted into an S1C17702 debug
signal, after which it is sent to the CPU board.The debugger on your PC can be used to download programs or
data to the CPU board, or debug programs by controlling their execution and stop.
CPU operating mode
A BRK instruction or debug interrupt (such as forcible break with the debugger) from the ICD board causes the
target CPU (the S1C17702 on the CPU board) to stop executing the target program and enter into debug mode (or
break state).In this state, commands can be executed from the debugger on your PC.The LED on the ICD board
lights in green during debug mode.The state in which the target CPU is executing a target program is called
normal mode.The LED on the ICD board lights in red during normal mode.
Connection and start-up
The procedures for making connections and for starting up the SVT17702 to implement a simple software
development environment are described below.
(1) Connect the ICD board with the CPU board. (Connect the 10-pin connector on the JICD board to the
matching connector on the CPU board as shown in the connection diagram in Chapter 14.)
(2) Connect the ICD board to your PC via a USB cable.
(3) When the USB Driver Installation Wizard appears on your PC, install an appropriate driver.(This step is
required only for the first connection. It is not required for the second connection and afterward.)For the
installation procedure, see the later section “Installing USB driver”.
(4) Make sure that the color of the LED on the ICD board changes from blue to green (the target is in debug
mode).
(

5 Operating Environment and Start-Up Procedures
5.2 Standalone Operation of SVT17702
The SVT17702 allows the CPU board to operate standalone without using the ICD board or PC.
Standalone operation
In this operation environment, the S1C17702 on the CPU board operates in normal mode to execute a program
written in the built-in flash memory.Therefore, a user program must be downloaded into the flash memory
contained in the S1C17702 in advance.(The SVT17702 is shipped with a demo program preloaded into on-chip
flash memory.)(For information about how to download a user program to the on-chip flash memory, see the
"S5U1C17001C Manual (S1C17 Family C Compiler Package)".
Connection and start-up
The procedure for operating the SVT17702 in a standalone mode is described below.
(1) Turn on the PC(if it is turned off).
(2) While the ICD board is connected with the CPU board, connect your PC to the ICD board via USB cable.
(3) Start the debugger on your PC and download a user program to the on-chip flash memory on the S1C17702.
For information about downloading a program, see the “S5U1C17001C Manual (S1C17 Family C Compiler
Package).”
(4) After exiting the debugger, remove the USB cable to disconnect the ICD board from your PC.
(5) Disconnect the ICD board from the CPU board, and install a coin cell battery.
(6) Press the reset switch on the CPU board.Then the S1C17702 on the CPU board starts executing a user pro-
gram downloaded to the flash memory.
