(ICDMINI VER1.0 and VER1.1)
Explanation of Terms (various modes)
S5U1C17001H (ICDmini)
ICD mode Flash programmer mode
This mode is for debugging the target.
The debugging requires a PC and the debugger gdb
(included in the S5U1C17001C S1C17 Family C Compiler
Package).
This mode is for programming the Flash of the target
without a PC used. Befo r e p r o g ramming c a n b e
performed, the program to be written must be loaded to
the S5U1C17001H (ICDmini) in ICD mode.
Debugger gdb (included in the S5U1C17001C S1C17 Family C Compiler Package)
Connect mode
Simulator (SIM) mode ICD Mini mode
The simulator mode simulates the target program
execution on the PC memory and no other tools are not
required. However, the debug functions depending on the
ICD cannot be used.
This is the mode to debug the target program using the
S5U1C17001H (ICDmini) or ICD board. The program
will be executed on the target board. The S5U1C17001H
(ICDmini) must be used in this mode.
Target (S1C17xxx)
Normal mode Debug mode
The normal mode is the normal state while the target is
executing the user program.
The target enters debug mode by one of the conditions
shown below.
• When a beak condition set by the debugger gdb has

In this mode, the target accepts the control by the
debugger gdb.
Various debugging operations, such as display and
rewriting the registers/memory, can be performed.
The target enters this mode when executing the startup
sequence after connecting it to the S5U1C17001H
(ICDmini).

1 Overview
S5U1C17001H USER MANUAL Seiko Epson Corporation 1
(ICDMINI VER1.0 and VER1.1)
1 Overview
The S5U1C17001H (ICDmini) is a hardware tool (emulator) that allows software to be efficiently developed for the
S1C17 Family of 16-bit processors*. The S5U1C17001H provides a software development environment with the
debugger (gdb.exe) by communicating it to the S1C17 processor on the target system and the debugger. In addition
to debugging, it can be used as a Flash programmer to program the Flash memory built into the S1C17 processor
on the target system as flash writer at main unit.
This manual primarily explains how to use the S5U1C17001H. For details on the debugger functions and
commands, refer to the “Debugger” section in the “S5U1C17001C Manual (C Compiler Package for S1C17
Family).”

The following shows the name of each part of the S5U1C17001H.
3.1 Left Side Panel
4-pin Flash programming power supply connector (white) 4-pin target interface connector (black)
GND pin BRK IN pin DIP switch
Left Side Panel
4-pin target interface connector (black)
This connector is used to input/output the debug signals (DCLK, DSIO, and DST2) from/to the S1C processor
on the target system. See Section 4.1.1, “Target Interface Connector,” for the pin assignment and connection.
4-pin Flash programming power supply connector (white)
This connector is used to output the reset signal to the target system and to supply a power voltage for Flash
programming (Note). Also it is used to input the target operating voltage when the target system voltage level is
used for the debug signal interface. See Section 4.1.2, “Flash Programming Power Supply Connector,” for the
pin assignment and connection.
Note: The S5U1C17001H is equipped with a 7-V Flash programming power supply with output
capacities of 30mA. Note, however, that its usage depends on the S1C processor. Be sure to
avoid using this power supply for the S1C processor (do not set SW8 of the DIP switch to ON) if
its technical manual does not describe the usage of the Flash programming power supply, as the
chip may be destroyed due to overvoltage. This pin must be left open if the connector is attached
on the target system.
DIP switch
The DIP switch assembly is used to select the target CPU core, Flash programmer mode, DSIO signal level,
connection test feature, firmware update feature, and Flash programming voltage output.

In ICD mode, the debugger on the PC controls the S5U1C17001H to execute the debug commands. (See Chapter 5.)
In Flash programmer mode, the S5U1C17001H operates as a standalone Flash programmer. (See Chapter 6.)

Note: The S5U1C17001H is equipped with a 7-V Flash programming power supply with output
capacities of 30mA. Note, however, that its usage depends on the S1C processor. Be sure to
avoid using this power supply for the S1C processor (do not set SW8 of the DIP switch to ON) if
its technical manual does not describe the usage of the Flash programming power supply, as the
chip may be destroyed due to overvoltage.
BRK IN pin
In ICD mode, if a Low level signal is input to this pin when the target program is being executed, execution of
the target program is suspended. After a Low level is input to the BRK IN pin, a break will occur after a few
instructions have been executed.
In Flash programmer mode, inputting a Low level to this pin has the same effect as pressing the RESET/
START switch (it starts erasing/writing/verification).
Note: The voltage to apply to the BRK IN pin must be 0 V for low level and 3.3 V or open for high level.
The BRK IN pin is always pulled up to 3.3 V.
GND pin
Connect this pin to the GND level (0 V).
