PDI Programming

All AVR XMEGA devices have the new PDI programming and debugging interface. It can, in-system, download code into the Flash application and boot memories, EEPROM memory, fuses, lock-bits, and signature information.



The PDI interface requires two of the deviceʼs pins; PDI_DATA and PDI_CLOCK. On STK600, they are found on the ISP/PDI connector.
