A target interface is a mechanism for communicating with and controlling a target. A target can be either a physical hardware device or a software simulation of a device. CrossStudio has a targets window for viewing and manipulating target interfaces. For more information on the targets window, see Targets window.

Before you can use a target interface, you must connect to it. You can only connect to a single target interface at any one time. For more information on connecting target interfaces, see Connecting to a target.

AVR core simulator target interface
  A software-simulated AVR core that supports program download and debugging. The software simulator is an effective way of testing and debugging programs in a simulated environment.
JTAG ICE target interface
  A target interface which supports the Atmel JTAG ICE that supports program download to flash and debugging. Using the JTAG ICE you can debug applications on your target board.
JTAGICE mkII target interface
  A target interface which supports the Atmel JTAGICE mkII that supports program download to flash and debugging. Using the JTAGICE mkII you can debug applications on your target board.
STK500-High Voltage target interface
  A target interface which supports the Atmel STK500 parallel and serial high voltage programming of flash.
STK500-ISP/AVRISP target interface
  A target interface which supports the Atmel STK500-ISP or Atmel AVRISP programming of flash.
AVRISP mkII target interface
  A target interface which supports the Atmel AVRISP mkII programming of flash.
