* - Minimum ISP target clock speed of 500KHz due to hardware SPI module prescaler limitations
* - No reversed/shorted target connector detection and notification
* - A seperate header is required for each of the ISP, PDI and TPI programming protocols that the user wishes to use
* - XMEGA EEPROM erase section command does not work (but EEPROM read/write and chip erase does)

* On AVR models with an ADC converter, AVCC should be tied to 5V (e.g. VBUS) and the VTARGET_ADC_CHANNEL token should be
