EXPLANATION OF TERMS
ii EPSON S5U1C17001H USER MANUAL
(ICD MINI VER. 1.0)
Explanation of Terms (various modes)
S5U1C17001H (ICD Mini)
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. Before programming can be
performed, the program to be written must be loaded to
the S5U1C17001H (ICD Mini) 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 (ICD Mini) or ICD board. The program will
be executed on the target board. The S5U1C17001H (ICD
Mini) 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
met
•When the break button on the gdb window is clicked
while the debugger is connected to the target
•When a low level signal is input to the DSIO pin of the
target
•When the CPU executes the brk instruction
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 (ICD
Mini).

4.1.1 Target Interface Connector
The 4-pin target interface connector (black) on the S5U1C17001H is used to input/output the debug signals from/
to the S1C processor on the target system. Use the target interface cable attached to the S5U1C17001H to connect
between this connector and the target system. This connection is always required to perform debugging. The pin
assignment of the 4-pin connector (black) on the S5U1C17001H is shown in the table below. For the debug pin
numbers on the S1C processor, refer to the technical manual of each model.

Notes: •Set the interface level (3.3 V/1.8 V/target input) using the DIP switches SW4 and SW5, and
select the CPU Core using the SW1 according to the target system before connecting the tar-
get system.
•The signals connected to the S5U1C17001H are very high-speed signals, so the connector
on the target system must be mounted within 5 cm from the S1C processor. If there is more
distance between the connector and the S1C processor, the S5U1C17001H may not work
properly.
•When wiring the S1C processor to the target connector for connecting the S5U1C17001H, in-
sert a 33 Wresistor in series between the S1C processor DSIO pin and the connector. This re-
sistor must be placed as close to the S1C processor as possible. Although the system can op-
erate without this 33 Wresistor, we recommend inserting this resistor to prevent malfunctions.
The other pins are connected directly. A low-level input to the DSIO pin issues a forced break
to set the S1C processor into debug mode. Although this signal is pulled up through about 100
kWinternally, when not debugging, we recommend either removing the 33 Wresistor to reduce
noise and other problems or pulling this line up to the VDD level (the core voltage).
•Be sure to use the supplied 4-pin cable for connecting the target system to the S5U1C17001H.
Using another cable may cause a malfunction. If another cable must be necessarily used, do
not extend the target interface cable and connect the cable directly to the S5U1C17001H so
that the distance to the S1C processor on the target system will be shortest.
•The 4-pin connector does not have a projection for preventing reverse insertion. Check the
cable color (blue) of pin 1 to be sure the insertion of connector is proper when connecting it to
the target system.

The 4-pin Flash programming power supply connector (white) is used to output a reset signal and a Flash pro-
gramming voltage to the target system, and to input the target interface voltage. These signals are not necessary
for debugging. Connect between this connector and the target system using the Flash programming power sup-
ply cable attached to the S5U1C17001H as necessary. The pin assignment of the 4-pin connector (white) on the
S5U1C17001H is shown in the table below.

Target voltage input (TARGET VCC IN)
In addition to 3.3 V and 1.8 V, the S5U1C17001H is capable of interfacing with the target system using the
voltage (1.0 to 5.0 V) input from the target system. To use this function, set SW4 to ON and input the target
voltage to the TARGET VCC IN pin.
Flash programming voltage output (FLASH VCC OUT)
Depending on the Flash memory module built into the S1C processor on the target system, its programming
voltage (7 V) can be supplied from the S5U1C17001H. The maximum current that can be supplied is 200 mA.
To use this output, set SW8 to ON and connect between the FLASH VCC OUT pin and the power supply pin
on the target system. When SW8 is set to ON, the FLASH VCC OUT pin always outputs a 7-V voltage regard-
less of whether the RESET/START switch is pressed or not.
Note: Refer to the technical manual of each model as to whether the target S1C processor is operable
with this voltage or not. Do not use this voltage unless there is a description about the usage in
the technical manual, as the S1C processor may be destroyed due to overvoltage.
