<snip> When the jtag ice boxes stopped succesfully the target during a debugger session, then the target is to be in a so called debugging state. Only during this debugging state the OCDR will be visible and the avr core will exchange data with the jtag ice boxes. When the jtag ice boxes terminate this debugging state then they can / will disable the OCDEN fuse bit. AVR studio debugger doesnot know anything about this debugging state as this will be managed only by the jtag ice boxes. This also means that during a running application the OCDR isnot visible.
