The debugWIRE On-chip debug system uses a One-wire, bi-directional interface to control the
program flow, execute Atmel
non-volatile memories.
When the debugWIRE Enable (DWEN) Fuse is programmed and Lock bits are unpro-
grammed, the debugWIRE system within the target device is activated. The RESET port pin is
configured as a wire-AND (open-drain) bi-directional I/O pin with pull-up enabled and becomes
the communication gateway between target and emulator.

source selected by the CKSEL Fuses.
