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.)

The target operating voltage should be input to Pin 4 on the Flash programming power supply connector.
enabling the connection test (SW6)
The connection test is a communication diagnostic feature at start up of the debugger.
Setting firmware update mode (SW7)
When SW7 is set to ON, a connection between the S5U1C17001H and the debugger can be established even if a
target is not connected. See Chapter 7, "Firmware Update," for how to update the firmware.
enabling voltage output for Flash programming (SW8)
note: The S5U1C17001H is equipped with a 7-V Flash programming power supply with output capaci-
ties of 200 mA. Note, however, that its usage depends on the S1C processor. Be sure to avoid us-
ing this power supply for the S1C processor (do not set SW8 of the DIP switch to ON) if its techni-
cal 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, the target
program execution is suspended. After a low level is input to the BRK IN pin, a break will occur after a few in-
structions have been executed.
In Flash programmer mode, inputting a low level to this pin has the same function as pressing the RESET/
START switch (it starts erasing/programming/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).
