The Atmel JTAG ICE target interface provides access to Atmel’s JTAG
ICE Mk I. This target interface supports program loading and debugging and access
to the fuse and lock bits. When debugging with the JTAG ICE you will have access
to four hardware breakpoints, however one of these breakpoints will be needed for single
stepping. Two of the hardware breakpoints may be used as data breakpoints.
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 Version
- The hardware version of the JTAG ICE.
- Software Version
- The software version of the JTAG ICE.
- Target Clock Frequency
- Specifies the target clock frequency - this is used to compute the
JTAG clock frequency.
Current property group
- Device Type
- The AVR device type, identified from the signature bytes.
- Fuse Bits
- The fuse bits of the device. A device specific fuse bits editor is invoked
on edit.
- JTAG ID
- The JTAG id.
- Lock Bits
- The lock bits of the device. A device specific lock bits editor is invoked
on edit.
- Oscillator Callibration Bytes
- The oscillator callibration bytes of the device.
- Signature Bytes
- The signature bytes of the device.
- Target Voltage
- The target voltage.
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.
