*
* \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
*
* The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
*
* <table>
* <tr>
* <td><b>Define Name:</b></td>

* <td><b>Description:</b></td>

# Processor frequency.
# This will define a symbol, F_CPU, in all source code files equal to the
# processor frequency. You can then use this symbol in your source code to
# calculate timings. Do NOT tack on a 'UL' at the end, this will be done
# automatically to create a 32-bit value in your source code.
# Typical values are:

# This will define a symbol, F_CLOCK, in all source code files equal to the

# raw input clock is fed directly to the PLL sections of the AVR for high speed

# at the end, this will be done automatically to create a 32-bit value in your
