TARGET VCC IN
I
Target voltage input
When an external power supply voltage (1.0 V to 5.5 V) is
used for interfacing between an ICDmini and a target system,
it should be input from the target system to this pin.
When using the interface voltage generated in the ICDmini,
leave this pin open and select the voltage level from 3.3 V and
1.8 V using the DIP switch. For the DIP switch setting, refer to
Table 5.5.1, “ICDmini DIP Switch Setting.”
Connect each ICDmini with a target system and supply power to the target systems.
Figure 7.2.2 Multi-Programming System Configuration Diagram
When connections are completed, press the reset buttons on the ICDminis. If the “New hardware search wizard”
starts on the PC after that, install the USB driver. For the location of the USB driver, refer to “5.3 Confirming and
Updating ICDmini Firmware.”
