Abstract

PURPOSE: To shorten the time used for interrupt processing by sending the first interrupt signal to the data processor after performing transmission and recption by means of a transmission-reception starting signal.
CONSTITUTION: This unit equips transmission mode FF1 which is set by transmission-reception starting signal 10A and is reset by transmission finish signal and control code detector FF3 which is set by control code 14 in the reception data which are sent from data terminal equipment 8 to data processor 7. Moreover, the transmission-reception control unit is constituted by setting reception mode FF2 which is set by signal 11A and is reset by output signal 17A of "or" gate 4 obtained by reception finish signal 16A outputted from data processor 7 and control code detecting signal 15A outputted by FF3, command operation finish signal generating circuit 5 which operates by means of signal 17A, and interrupt FF6 which is set by command operation finish signal 18A of circuit 5 and is reset by reset signal 20A sent from data processor 7.
