Abstract

PURPOSE: To make possible the connection of character disassembling and assembling controllers having different number of circuits accommodated, by providing signal lines indicating the number of circuits to be accommodated, thereby making accommodation of circuits from high-speed to low-speed ones, without lowering the maximum number of circuits accommodated.
CONSTITUTION: Controllers 3 and 16 are established which input the values of counter 1 through signal line 2 and control the disassembling and assembling of characters through n-circuit and n/2-circuit, and the outputs of signal lines 5 and 6 are inputted to request receiving circuit. Also signals of signal lines 11 and 12 are selected by selection circuit 14, and set addresses from the respective controllers 3 and 16 and output from circuit 7 to the interrupt request register 4; and thus control of controllers 3 and 16 having different number of accommodated circuits is made possible by means of the signal lines 11 and 12 which indicate the allowable maximum number of circuits to be accommodated.
