Abstract

PURPOSE: To share a circuit stored with pieces of information different in stay time by providing a pair of storage methods of storing data from a shared data bus, a method selecting either one of two storage methods, and a method selecting two operation modes.
CONSTITUTION: When input-mode determing FF8 assigns a switching mode, the 1st data are stored in register 1 via data bus 10 by control part 3. At this time, data holding indication part 6 turns ON and control part 3 becmoes ready to store data in register 2. Once the 2nd data are supplied via bus 10, control part 3 stores the data in register 2 and data holding indication part 7 turns ON. At the same time, control part 3 becomes ready to store data in register 1. With indication part 6 ON, control part 5 outputs the data of register 1 to bus 30 via switching part 4. By repeating signals from control parts 3 and 5, data are stored in registers 1 and 2 alternately. When FF8 assigns a fixed mode, data are stored only in register 1 and sent out.
