debugWIRE is a debugging protocol for Atmel AVRs.

Protocol

debugWIRE is used for on-chip debugging (OCD) of Atmel AVR microprocessors. It is simpler than JTAG and only uses a single pin. It is aimed at small processors where full JTAG is not an option. It is supported by most modern 8-bit AVRs. By using debugWIRE you have full read and write access to all memory and full control over the execution flow.

Programmers

There are 3 programmers that support debugWIRE. All are made by Atmel: AVR Dragon, AVR JTAGICE mkII and AVR One.
