Abstract: Easy testability and data security of an electrically erasable programmable read only memory (EEPROM) can be accomplished by disposing pads and an input/output (I/O) circuit providing addresses, data and control signals necessary for the EEPROM test on a semiconductor substrate and by disposing a two-level test I/O interception circuit consisting of an EEPROM device on the substrate such that once the testing is completed, unauthorized accessing is prevented from outside the semiconductor substrate as a result of having a built-in data security function. A microcomputer having this capability is provided with a central processing unit (CPU) for processing data, a memory, such as an EEPROM, which is internally communicating through a common bus (which transmits data, address and control signals) with the CPU, other than during a test mode, and first and second inhibition circuits which provide the security.

Abstract: A control system for an automotive vehicle controls driving torque delivery for driven wheels. The control system basically controls an output torque of an automotive internal combustion engine toward a target engine output torque which is derived on the basis of an accelerator operational magnitude. The target engine output torque can be modified according to associated conditions, such as road friction level, a characteristic of a power train including a torque converter and a power transmission. The control system also performs selection of engine output control and transmission shift control depending upon vehicle driving condition.
