The debugWIRE On-chip debug system uses a One-wire, bi-directional interface to control the
program flow, execute AVR
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.

tor connector. The system clock is not affected by debugWIRE and will always be the clock
source selected by the CKSEL Fuses.
