Performance
- On-Chip Debugging: Run, Single step, Breakpoints, etc. Allows the user to view the internal state of the device.
- High speed Debugging
- Programming Interface to flash, eeprom, fuses and lockbits (not debugWIRE)
- Low speed programming through ISP, or high speed programming through JTAG
Connecting to PC
Before connecting up the JTAGICE XPII for the first time, be sure to install the USB driver on the host computer. This is done automatically when installing the front-end software (Probably AVR Studio). The JTAGICE XPII can connect to the host PC through a USB cable or serial cable (to COM port on the PC)
- Each JTAGICE XPII has a unique ID, a PC could connects to several Devices at the same time
- USB Interface: use the PDIUSBD12, USB 1.1
- RS-232 Interface: use the 9-pin RS-232 cable. Make sure that no other software has control of the COM port where the JTAGICE XPII is connected.
The rear panel of the JTAGICE XPII houses the DC jack, power switch, USB and RS-232 connectors.
Connects to target board
Debugging Interface: JTAG, PDI, debugWIRE (SPI), depending on which interface the target devices with.
Programming Interface: JTAG, PDI, ISP (SPI), depending on which interface the target devices with.
The cable has to be changed according to the existed header on the target board. See Details displayed bellow.
The figure 1, 2, 3 and 4 shows the header pinouts of different interfaces

Powering the JTAGICE XPII
- Operates using an external power supply providing 9-15V DC
- Can be powered directly from the USB bus
- The target board should be powered from Another Power Supply
