INTERFACE DEVICE OF CORE AND PERIPHERAL CIRCUIT

摘要

PURPOSE: An interface device between an internal and a peripheral circuit is provided to simply and variously control the peripheral circuit by adding a bit manipulation function. CONSTITUTION: An interface device between an internal circuit(21) and a peripheral circuit(22) transmits an address bus, an enable signal, the first and the second control signal to the peripheral circuit(22) from the internal circuit(21). The internal circuit(21) and the peripheral circuit(22) transmit and receive data through a data bus. The peripheral circuit(22) transmits an interrupt signal to the internal circuit(21).
