The Atmel JTAGICE mkII target interface provides access to Atmel’s JTAGICE mkII.
Both USB and serial port host PC connections are supported as is JTAG, debugWIRE and ISP
target connection. The JTAG and debugWIRE target connections support program loading
and debugging. The JTAG and ISP connections support access to the lock bits and
fuse bits. When debugging with the JTAG interface three hardware breakpoints are available for
use, however one of these breakpoints will be needed for single stepping. Two of the hardware
breakpoints can be used as data breakpoints. When debugging with the debugWIRE interface no
hardware breakpoints are available.
Target window specific context menu entries
- Disconnect (Disable debugWIRE).
- This requires the ISP connection as well as the debugWIRE connection and
will disable the DWEN fuse and disconnect.
- Fuse Bits.
- This displays the fuse bits editor.
- Lock Bits.
- This displays the fuse bits editor.
Connection property group
- Baud Rate
- The speed the serial port connection runs at.
- Port Name
- The name of the serial port.
- External Reset
- Specifies if an external reset is to be performed on JTAG device identify
and chip erase.
- Hardware Breakpoints
- If set then only hardware breakpoints will be used. If not set then software
breakpoints will be used unless a hardware breakpoint is specifically requested.
- Hardware Version
- The hardware version of the JTAGICE mkII.
- Serial Number
- The serial number of the JTAGICE mkII.
- Software Version
- The software version of the JTAGICE mkII.
- Target Clock Frequency
- Specifies the target clock frequency - this is used to compute the
JTAG clock frequency.
- USB Serial Number
- The serial numbers of the JTAGICE mkII. This is updated each time a USB
connection is made.
Current property group
- Device Type
- The AVR device type, identified from the JTAG ID or the signature bytes.
- Fuse Bits
- The fuse bits of the device.
- JTAG ID
- The JTAG id.
- Lock Bits
- The lock bits of the device.
- Oscillator Callibration Bytes

JTAG Daisy Chain
These properties can be used if the target AVR is in a JTAG Daisy Chain.
- Devices After
- The number of JTAG devices after the AVR target.
- Devices Before
- The number of JTAG devices before the AVR target.
- Instruction Bits After
- The combined number of IR bits of the devices after the target.
- Instruction Bits Before
- The combined number of IR bits of the devices before the target.
