Abstract
A circuit and method for providing a power-on self test capability for peripheral devices that allows direct testing of address-line data. The preferred embodiment includes a multiplexer circuit that allows the read address line outputs of a microprocessor to be directly returned to the data inputs of the microprocessor, thus providing a direct verification of the integrity of the read-address connection.
