Family manual for the Atmel AVR XMEGA D series, a 5.25 MB PDF describing the core, memories, clock system, power management, ports, timers, communication peripherals, ADC and the PDI programming interface at register level. It complements the per-device D3 and D4 datasheets, which hold pinouts and electrical values. Repair and firmware technicians use it to understand fuse settings, clock configuration and programming procedures before reading or writing a chip. Confirm the specific part against its own datasheet.
