Abstract

PURPOSE:To realize the miniaturization, the low price and high reliability by providing an input output control part composed of one control LSI including a CPU chip, plural input output ports which are assembled with the block of an individual input output port respectively and in which the macro cell is implemented and the chip selection connected to an input outer control part and respective input output ports. CONSTITUTION:When an electric power source is turned on, an input output control part 1 in an LSI for the control circuit initializes of the internal circuit and thereafter, successively, initializes respective LSIs 21-25 for the input output port by using a chip selecting 3. Especially, these LSIs 21-25 for the input output port have the parallel input output port of 10 ports, 9 ports out of them have the action form of the input port, the output port, the hand shaking, the bit setting, etc., and therefore, the form is designated so that the action form, which is respectively necessary, can be obtained. Since one remaining port is the form for the output port only, the initialization of the action form is not necessary, and it is necessary to designate the initialization bit by bit.

y-yp, o2 is the control circuit, 03-01B are each C
These are various input/output ports controlled by the P U f-y port 1 and the control circuit 02. Each of these input/output ports 03 to 018 is a general-purpose input/output port L8.
For example, about 15 chips in a 40-bin DIP package are required. Therefore, in the conventional example shown in Fig. 2, the mounting area of the control circuit is large, and the number of parts increases because a large number of LSIs for input/output ports are used, which increases cost and reduces reliability. There was a drawback.

The input/output control section is made smaller by configuring it with a single control LSI including a CPU chip, instead of combining multiple ICs as in the past. In addition to lowering costs and achieving high reliability, we aim to shorten the LSI development period by combining input/output ports that are often slow with conventional individual input/output capo) IC blocks and converting each into a macro cell. Furthermore, by configuring the logic circuit of the main control section using far fewer chips than conventional ones, it is possible to use a single printed circuit board.
