Abstract:
The present invention provides a system and method for protecting data stored in the control registers of an integrated circuit, such as a television chip. The system and method use one or more selectively activated read protection modules to prevent the control registers from being read unless a predetermined key or password is entered. The password or key may be stored in password registers within the chip. A key access generator will enable read access of the control registers if correct values are written to the appropriate password registers. The key access generator may enable read access for a predetermined period of time or until it receives another input.

Claim (Index 36):
A system, comprising:\n a central processing unit (CPU); and a digital television chip operable to prevent unauthorized access to a performance parameter, wherein the digital television chip comprises:\n an audio processor configured to customize an audio quality according to the performance parameter; \n a control register configured to store the performance parameter; and \n a read protection circuit configured to prevent the performance parameter from being read out of the control register by the CPU, wherein the read protection circuit is configured to prevent the performance parameter from being read out of the control register to a port while simultaneously allowing the performance parameter to be read out of the control register to the audio processor, and wherein the read protection circuit comprises a serial port and a parallel port, and wherein access to the performance parameter via the serial port is selectably enabled and independent of whether access to the performance parameter via the parallel port is enabled.
