1.1 Directions for Use
An S1C17656 software debugging and evaluation environment can be constructed with the procedure shown
below.
<When performing software debugging>
(1) The S5U1C17656T has through hole electrodes for the debug signals but does not provide components
required for the debug interface such as connectors to connect with the 4-pin target interface cable and 4-pin
flash programming power supply cable supplied with the S5U1C17001H (ICDmini).
To perform software debugging using this board, prepare the components required for connecting with the
ICDmini.
(2) Supply power to the S5U1C17656T by putting a coin type battery (CR2032, 3.0V) into the battery holder, or
connecting the power supply cable of the S5U1C17001H2 (ICDmini Ver. 2) or a stabilized power supply to
the terminals of the battery holder. The power supply voltage must be within the S1C17656 operating
voltage range (1.8 V to 3.6 V when programming the flash memory embedded in the S1C17656).
(3) Connect the ICDmini to the PC using the USB cable supplied with the ICDmini.
The DIP switches on the ICDmini (SW4 and SW5 to select the DSIO signal level) should be set to “Voltage input
from the target system.” If the S5U1C17001H2 (ICDmini Ver. 2) is used as the emulator and the flash
erasing/programming voltage is supplied from the ICDmini, set DIP SW8 on the ICDmini to configure the flash
programming voltage output to be enabled.
