+ *  \section Sec_Running Running the Bootloader
+ *
+ *  This bootloader is designed to be started via the HWB mechanism of the USB AVRs; ground the HWB pin (see device
+ *  datasheet) then momentarily ground /RESET to start the bootloader. This assumes the HWBE fuse is set and the BOOTRST
+ *  fuse is cleared.
+ *

+ *  Ground the USB AVR JTAG's \c TCK pin to ground when powering on the board to start the bootloader. This assumes the
+ *  \c HWBE fuse is cleared and the \c BOOTRST fuse is set as the HWBE pin is not user accessible on this board.
