S5U1C33001H1400 Manual (Rev. 0.20)
1. GLOSSARY
S5U1C33001H1400 (ICD33V6.0)
ICD mode Flash programmer mode
This mode is used to debug the target system. Debugging
requires both a PC and the debugger (gdb. exe included in
the S5U1C33001C: C Compiler Package for S1C33
Family).
This mode is used to write programs to the target
system without a PC. Before writing a program to the
target system, you must load the program to the
S5U1C33001H1400 (ICD33V6.0) in ICD mode.
Debugger, gdb.exe (included in the S5U1C33001C: C Compiler Package for S1C33 Family)
Simulator (SIM) mode ICD6 mode
This mode simulates the execution of the target program on
a PC memory. This mode does not require any other tool.
However, this mode cannot execute ICD-dependent
functions.
This mode performs debugging using the
S5U1C33001H1400 (ICD33V6.0) or ICD board. The
program is executed on the target board. To debug
these products, use this debugger in ICD6 mode.
Target (S1C33xxx)
Normal mode Debug mode
Ordinary mode in which the target system executes a user
program.
The mode changes to debug mode under the following
conditions:
•When the break condition set by the debugger (gdb.exe)
is met
•When the user presses the Break button on the gdb
screen while the debugger (gdb.exe) is connected
•When a Low level is input to the target system DSIO pin
•When the CPU executes a brk command
In this mode, the target system accepts control by the
debugger (gdb.exe).
This mode permits various debugging operations,
including display and rewriting of data in registers and
memory.
This mode is activated when the S5U1C33001H1400
(ICD33V6.0) is connected and the power-on sequence
is executed.

4. NAME AND FUNCTION OF EACH PART
The following shows an external view of the S5U1C33001H1400’s operating section and the name of each part.
4.1 Left-side panel
Fig. 3 Left-side panel
4.1.1 10-pin connector for connecting to target systems
This connector is used to connect to the target system using a 10-pin cable or 10-pin-4-pin cable.
4.1.2 30-pin connector (not provided) for connecting to target systems
This connector is used to connect to the target system using a 30-pin cable.
Note: This connector is not provided with the debugger unit. Please contact us if you need
this cable.
Note: Only one of the 10-pin connector for connecting to target systems and 30-pin
connector for connecting to target systems may be used at any given time.
4.1.3 4-pin connector for flash programmer power supply
This connector is used to output a reset signal to the target system or to supply power
(note) for flash programming. When the interface for debug signals requires a voltage level
for the target system, this connector is used to input the operating voltage from the target
system. For information on the connector pin configuration and connection method, refer
to “Connector for flash programmer power supply.”
Note: The S5U1C1700H incorporates a 7-V, 200-mA power supply for flash programming.
However, use of this power supply may not be possible with certain S1C processors.
If the technical manual for the target S1C processor does not specifically mention
this power supply, damage may occur in the chip due to overvoltage. To prevent this
problem, avoid using this voltage (do not set the DIP SW8 to ON) if this voltage is
not supported by the target S1C processor. Keep this pin open when implementing a
connection terminal on the target board.

4.1.4 Regarding the monitor pins
•GND pin (black (left side in the above diagram))
To monitor the signals output from the above pins, connect the GND of a measuring
instrument such as an oscilloscope to this pin. If the ground level between the
S5U1C33001H and the target system is unstable (particularly when the 4-pin cable is
used), this pin can be used to stabilize the ground level.
•BRK IN pin (red)
If a low-level signal is input to this pin when the target program is being executed, the
target program execution is suspended. After a low level is input to the BRK IN
terminal, a break will occur after a few instructions have been executed.
•TRC IN pin (white)
This pin inputs an external trace signal. The input signal can also be traced when the
bus trace is performed.
•TRG OUT pin (light blue)
The TRG OUT pin outputs trace trigger signals indicating the start and end of the trace.
To perform an area trace with the S5U1C33001H, set two trigger points: the start
address and end address of the trace area. When the execution address of the program
corresponds to the set trace trigger point, the TRG OUT pin outputs a High-level signal.
It also outputs a High-level signal when target program execution is suspended. For a
discussion of how to set the trace function, see the “Debugger” section in the
S5U1C33001C Manual (C Compiler Package for S1C33 Family). The output timing is
shown below. To generate trace trigger signals, you must run the program for trace
trigger point 1 and point 2, in that order. Shown below are states in which trace triggers
are and are not generated.

•EMUOUT pin (green)
This pin outputs a low level when the EMU/ERASE LED is lit (that is, when the
program is being executed) and outputs the 5 V level when that LCD is off (during a
break). This signal can be used as the protect signal for the S5U1C33xxxM emulation
memory.
•TRCFULL pin (blue (right side in the above diagram))
This is the trace full state output pin. This pin outputs a high level when the trace
memory becomes full.

4.2.2 RESET/START switch
< In ICD mode >
Pressing the RESET/START switch restarts the firmware and establishes an initial
connection with the target S1C processor. If the target board is not connected, the firmware
awaits the initial connection. If the TARGET RST OUTPUT signal from the
S5U1C33001H reaches the target board, a reset signal is also output.
< In flash programmer mode >
Pressing the RESET/START switch invokes the selected flash operation function (erase,
write, verify). If the LED indicates OK/ERR, the state immediately before the execution of
the function will be restored.
Note: After operating the DIP switches, press the RESET/START switch to apply the
settings (in ICD mode or flash programmer mode).
4.2.3 USB connector
This connector is used to connect a PC using the USB cable.
Note: A USB hub that runs solely on bus power may not provide adequate power in all
cases. To supply voltage for flash programming to the target system in flash
programmer mode, connect directly to the USB port of the PC or use an AC adaptor
(USB 5-V output) to supply power to the USB cable.

LED1 through LED4
The four LEDs on the top panel show the debugging or flash programming status of LED1 through
LED4 on the front panel. The information provided by these LEDs in ICD mode and flash
programmer mode differs.

LED1 (CPU)
This LED indicates the target CPU selected by the DIP SW1.
(Green) C33: Product incorporating S1C33xxx or S1C33 core
(Blue) C17: Product incorporating S1C17xxx or S1C17 core (not supported at this time)
LED2 (ICD MODE)
This LED emits a constant red light if the target system is not connected and flashes red if a proper
connection cannot be achieved with the target system. The LED signals continuous blue if ICD mode
is selected (DIP SW2 and SW3 set to OPEN).
(Blue) Operations in ICD mode
(In initial connection)
(Yellow) USB is being recognized
(Red, ON) Target system is not connected
(Red, flashing) Communication with target system cannot be achieved
