* This project serves a dual purpose. When loaded into the USB AVR on the XPLAIN board, it will act as either a USB to Serial\r
- * converter for the XPLAIN's hardware USART (at a speed of 9600 baud), or a PDI programmer for the XMEGA. This project replaces\r
- * the firmware preloaded onto the XPLAIN's onboard AT90USB1287 microcontroller.\r

- * When inserted, the JTAG port's TDI pin is read. If the pin is left high, the device will enumerate as a regular COM port on\r
- * the host, which can then be opened and data exchanged between the XMEGA and Host as if the XMEGA was connected directly to\r
- * the host's serial port. If the pin is pulled low, the device will enumerate as an AVRISP-MKII to the host, so that the XMEGA\r
- * can be reprogrammed by AVRStudio or other compatible software such as avrdude.\r
+ * When power to the board is applied, the TDI pin (pin 9) of the USB AVR's JTAG port is read. If the pin is left high, the device\r
+ * will enumerate as a regular COM port on the host, which can then be opened and data exchanged between the XMEGA and Host as if\r
+ * the XMEGA was connected directly to the host's serial port. If the pin is pulled low by shorting it to GND (pin 10), the device\r
+ * will enumerate as an AVRISP-MKII to the host, so that the XMEGA can be reprogrammed by AVRStudio or other compatible software\r
+ * such as avrdude.\r

* After running this project for the first time on a new computer, you will need to supply the .INF file located in this project\r
* project's directory as the device's driver when running under Windows. This will enable Windows to use its inbuilt CDC drivers,\r
* negating the need for custom drivers for the device. Other Operating Systems should automatically use their own inbuilt CDC-ACM\r
* drivers.\r
