Description
VTG 4 1 Target voltage reference. The Atmel-ICE samples the target voltage on this
pin in order to power the level converters correctly. The Atmel-ICE draws
less than 3mA from this pin in debugWIRE mode and less than 1mA in
other modes.
GND 2, 10 3, 5, 9 Ground. All must be connected to ensure that the Atmel-ICE and the target
device share the same ground reference.
4.4.3. SPI Physical Interface
In-System Programming uses the target Atmel AVR’s internal SPI (Serial Peripheral Interface) to
download code into the flash and EEPROM memories. It is not a debugging interface. When designing an
application PCB, which includes an AVR with the SPI interface, the pinout as shown in the figure below
should be used.

4.4.4. Connecting to an SPI Target
The recommended pinout for the 6-pin SPI connector is shown in Figure 4-10.
Connection to a 6-pin 100-mil SPI header
Use the 6-pin 100-mil tap on the flat cable (included in some kits) to connect to a standard 100-mil SPI
header.
Connection to a 6-pin 50-mil SPI header
Use the adapter board (included in some kits) to connect to a standard 50-mil SPI header.
Connection to a custom 100-mil header
The 10-pin mini-squid cable should be used to connect between the Atmel-ICE AVR connector port and
the target board. Six connections are required, as described in the table below.
Important:
The SPI interface is effectively disabled when the debugWIRE enable fuse (DWEN) is
programmed, even if SPIEN fuse is also programmed. To re-enable the SPI interface, the
'disable debugWIRE' command must be issued while in a debugWIRE debugging session.
Disabling debugWIRE in this manner requires that the SPIEN fuse is already programmed. If
Atmel Studio fails to disable debugWIRE, it is probable because the SPIEN fuse is NOT
programmed. If this is the case, it is necessary to use a high-voltage programming interface to
program the SPIEN fuse.
