   *  Marlin_AT90USB - https://github.com/Bob-the-Kuhn/Marlin_AT90USB
   *    This is the only known IDE extension that is compatible with the pin definitions
   *    in this file, Adrduino 1.6.12 and the latest mainstream Marlin software.
   *
   *    "Marlin_AT90USB" makes PWM0A available rather than the usual PWM1C. These PWMs share
   *    the same physical pin. Marlin uses TIMER1 to generate interrupts and sets it up such
   *    that PWM1A, PWM1B & PWM1C can't be used.
   *
   *  Installation:
   *
   *    1. In the Arduino IDE, under Files -> Preferences paste the following URL
   *       https://rawgit.com/Bob-the-Kuhn/Marlin_AT90USB/master/package_MARLIN_AT90USB_index.json
   *    2. Under Tools > Board -> Boards manager, scroll to the bottom, click on MARLIN_AT90USB
   *       and then click on "Install"
   *    3. Select "AT90USB646_TEENSYPP" from the 'Tools > Board' menu.
   */
  
  /**
   *  To burn the bootloader that comes with Marlin_AT90USB:
   *
   *    1. Connect your programmer to the board.
   *    2. In Arduino IDE select "AT90USB646_TEENSYPP" and then select the programmer.
   *    3. In Arduino IDE click on "burn bootloader". Don't worry about the "verify failed at 1F000" error message.
   *    4. The programmer is no longer needed. Remove it.
