A bus interface logic integrated circuit having a function of bus interfacing a system bus with a higher-order module, including a programmable chip connected between the system bus and the higher-order module and adapted to bus interface the system bus and the higher-order module with each other, the programmable chip initiating transmission and receipt of data under a control of the higher-order module. The programmable chip includes input/output units for selecting data input and output between the system bus and the higher-order module, a part of the input/output units being connected to the system bus and the other input/output unit part being connected to the higher-order module, and a combination logic unit for combining parameters generated for the transmission and receipt of data between each of the system bus-side input/output units and each corresponding one of the higher-order module-side input/output units and outputting a value required for the transmission and receipt of data on the basis of the result of the combination.
