Abstract:
A data processing apparatus is provided comprising data processing circuitry and debug circuitry. The debug circuitry controls operation of the processing circuitry when operating in a debug mode. The data processing circuitry determines upon entry into a debug mode a current operating state of the data processing apparatus. The data processing circuitry allocates one of a plurality of instruction sets to be used as a debug instruction set depending upon the determined current operating state.
