Notes Set the interface level 3 3V 1 8V 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 target system The signals connected to the S5U1C17001H are very high speed signals so the connector on the target system must be mounted within 5cm 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 insert a 33Q resistor in series between the S1C processor DSIO pin and the connector This resistor must be placed as close to the S1C processor as possible Although the system can operate without this 33Q resistor 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 100kQ internally when not debugging we recommend either removing the 339 resistor to reduce noise and other problems or pulling this line up to the Vpp level 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 distanc
