Abstract
A microprocessor-based system includes multiple peripherals, which can be accessed by the microprocessor over a system bus, with the aid of address decoding logic. Depending on the required functionality of the system at any time, one or more of the peripherals can be disabled. When a peripheral device is disabled, the address decoding logic of the system is modified to ensure that no attempts are made to access that peripheral device.
