Abstract
An integrated-circuit device comprising a non-volatile memory (NVM), a debug port, and debug-port control circuitry for controlling access to the integrated-circuit device through the debug port. The debug-port control circuitry is configured to read a first bit array and a second bit array from respective predetermined locations in the NVM in a single read cycle. The second bit array is distinct from the first bit array, and at least the second bit array contains a plurality of bits. The debug-port control circuitry is further configured to determine whether the first bit array has a first predetermined bit pattern and whether the second bit array has a pattern other than a second predetermined bit pattern, and to control access through the debug port at least partly in dependence on said determination.
