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, debugWIRE and ISP target connections support program loading. The JTAG and debugWIRE target connections support interactive debugging. The JTAG and ISP connections support access to the lock bits, fuse bits and signature/calibration bytes. 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.

###### Connection property group

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.

###### Connection property group - serial host connection

Baud Rate
  The speed the serial port connection runs at.
Port Name
  The name of the serial port.

###### Connection property group - USB host connection

USB Serial Number
  The serial numbers of the JTAGICE mkII. This is updated each time a USB connection is made.

###### Connection property group - JTAG target connection

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.
Target Clock Frequency
  Specifies the target clock frequency - this is used to compute the JTAG clock frequency.

###### Connection property group - ISP target connection

Device Name
  The device to be programmed.
ISP Freq (Desired)
  The ISP frequency which must be less than 1/4 of the target frequency.
Use Target As Device Name
  If this is set the Target project property of the current project in the current build configuration is used rather than the Device Name.

###### Current property group

Device Type
  The AVR device type, identified from the JTAG ID or the signature bytes.
Target Voltage
  The target voltage.

###### Current property group - JTAG target connection

JTAG ID
  The JTAG id.

###### 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.
