2.6 Debugging

2.6.1 Debugging with AVR JTAGICEmkII

The JTAGEN fuse must be programmed to enable the JTAG Test Access Port. In addi-

tion, the OCDEN fuse must be programmed and no Lock bits must be set for the Onchip

debug system to work. As a security feature, the On-chip debug system is disabled

when either of the LB1 or LB2 Lock bits are set. Otherwise, the On-chip debug system

would have provided a back-door into a secured device.

The AVR Studio enables the user to fully control execution of programs on an AVR

device with On-chip Debug capability, AVR In-Circuit Emulator, or the built-in AVR

Instruction Set Simulator. AVR Studio

supports source level execution of Assembly pro-

grams assembled with Atmel Corporation’s AVR Assembler and C programs compiled

with third party vendors’ compilers.

AVR Studio runs under Microsoft

Windows

95/98/2000/NT/XP. For a full description of

the AVR Studio, please refer to the AVR Studio User Guide.
