SEMICONDUCTOR DEVICE

摘要

A semiconductor device is packaged in a module and includes an interface arranged to perform data communication with outside of the device, and a detector arranged to detect whether or not a module output terminal is in a non-normal state. The module has a module power source terminal and a module output terminal, but has no data communication dedicated terminal. When the module output terminal is in the non-normal state, the interface uses the module output terminal or the module power source terminal so as to proceed to a module data communication mode for data communication with outside.

1. A semiconductor device packaged in a module, the device comprising:
an interface arranged to perform data communication with outside of the device; and a detector arranged to detect whether or not one of module output terminals provided to the module is in a non-normal state, wherein the module has a module power source terminal and at least one module output terminal, but has no data communication dedicated terminal, and when one of the module output terminals is in the non-normal state, the interface uses the module output terminal or the module power source terminal so as to proceed to a data communication mode for data communication with outside of the module.
