  *  Note that this design currently has several limitations:\r
  *    - Minimum target clock speed of 500KHz due to hardware SPI used\r
  *    - No reversed/shorted target connector detection and notification\r
- *    - PDI programming is not supported for XMEGA targets\r
  *\r
  *  On AVR models with an ADC converter, ACC should be tied to 5V (e.g. VBUS) and the VTARGET_ADC_CHANNEL token should be\r
  *  set to an appropriate ADC channel number in the project makefile for VTARGET detection to operate correctly. On models\r
  *  without an ADC converter, VTARGET will report at a fixed 5V level.\r
