Abstract
PURPOSE: To ensure the timing control without the timing control circuit.
CONSTITUTION: Each unit (51A to 52B) is commonly connected to the bus line, the unit of some groups 51a and 51B of each unit has the bus scramble circuit which disables to use the lower priority and enables to use the bus at any time when the unit having higher priority than itself does not use the bus, and informs the usage of the bus by interrupting the unit of the said groups when no bus scramble is present by each unit of the groups 51A and 51B, simultaneously inhibiting the bus scramble by the unit having the lower priority than itself one after another, to allow to have the logic for the bus scramble.
