INTERRUPT CIRCUIT IN CONTROL SYSTEM

摘要

The interrupt circuit enables a computer to do another jobs between transmitting data into control systems and receiving data from it. In control system comprising a master control unit to transmit/receive data to/from slave control units and a computer to transmit/receive control data to/from the master control unit, the interrupt circuit comprises the first D flip-flop (34) and the second D flip-flop (35) outputting according to control data (30) from master control unit and address decoding signal (31,33); the first clock divider (40); the third and the fourth D flip-flops (36,38); the first and the second inverters (37); tri-state buffer (39).
