1) Some devices require also other pins to be connected
to GND, this can be found in a picture in the device
datasheet in chapter "High-voltage Serial
programming".
AVR with TPI Interface (e.g.
ATtiny10)

ATxmega with PDI Interface

1) For programming that uses the JTAG interface,
devices must be connected as described in the JTAG
Interface section.
AVR with UPDI Interface
Fig.14: AVR microcontroller, UPDI interface
1) On UPDI pin a 12V pulse is used to enter the
programming mode of ATtiny UPDI.
2) When the programmed device quiets the
programming mode or the UPDI interface is disabled
during programming, a power-on reset of the
programmed device have to be done.
3) For AVR with UPDI data files with memories mapped
from zero are expected and their fuses save to a
project file same as for older AVRs, because Atmel
Studio creates the data files this way.
