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

* <td><b>Description:</b></td>
* </tr>
* <tr>
* <td>RESET_LINE_PORT</td>
* <td>Makefile CDEFS</td>
* <td>PORT register for the programmer's target RESET line.</td>
* </tr>
* <tr>
* <td>RESET_LINE_DDR</td>
* <td>Makefile CDEFS</td>
* <td>DDR register for the programmer's target RESET line.</td>
* </tr>
* <tr>
* <td>RESET_LINE_MASK</td>
* <td>Makefile CDEFS</td>
* <td>Mask for the programmer's target RESET line on the chosen port.</td>
