MICROCONTROLLERS JTAGICE mkII On-chip Debug DEBUG AVR APPLICATIONS USING System JTAG OR DEBUGWIRE INTERFACE The AVR JTAGICE mklI from Atmel is a powerful development tool for On-chip Debugging of all AVR 8-bit RISC microcontrollers with IEEE 1149.1 compliant JTAG interface or debugWIRE Interface. DebugWIRE enables on chip debug of AVR microcontrollers in small pin count packages, using only a single wire for the debug interface. The JTAGICE mkII and the AVR Studio user inter- face give the user complete control of the internal resources of the microcontroller, helping to reduce development time by making debugging easier. The JTAGICE mkII performs Real Time emulation of the microcontroller while it is running in a target system. The JTAGICE mkII provides emulation capability at a fraction of the cost of traditional emulators.
