Abstract
A storage device (200) has a memory and a circuit (100) which has a data input (Din), a control input (CTRL) and a data output (Dout), and provides an address input from the data input (Din) to the memory in accordance with a control signal from the control input (CTRL), so that the storage device (200) stores the data at the address in the memory or outputs data at the address in the memory to the data output (Dout). The apparatus provides the control signal to the control input (CTRL) from the interface (PORTS, P0, P1, P2), address and the data to the data input (Din) from the interface (PORTS, P0, P1, P2), to store the data at the address in the memory or to output data at the address in the memory to the data output (Dout). The apparatus may have a microcontroller (MPU) in which the interface (PORTS, P0, P1, P2) is provided.
