  50  *  \section SSec_Description Project Description:
  51  *
  52  *  Firmware for an AVRStudio compatible AVRISP-MKII clone programmer. This project will enable the USB AVR series of
  53  *  microcontrollers to act as a clone of the official Atmel AVRISP-MKII programmer, usable within AVRStudio. In its
  54  *  most basic form, it allows for the programming of 5V AVRs from within AVRStudio with no special hardware other than
  55  *  the USB AVR and the parts needed for the USB interface. If the user desires, more advanced circuits incorporating
  56  *  level conversion can be made to allow for the programming of 3.3V AVR designs.
  57  *
  58  *  This device spoofs Atmel's official AVRISP-MKII device PID so that it remains compatible with Atmel's AVRISP-MKII
  59  *  drivers. When promted, direct your OS to install Atmel's AVRISP-MKII drivers provided with AVRStudio.
  60  *
  61  *  Note that this design currently has several limitations:
  62  *    - Minimum target clock speed of 500KHz due to hardware SPI used
  63  *    - No VTARGET detection and notification
  64  *    - No reversed/shorted target connector detection and notification
  65  *
