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

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.
