ABSTRACT:
Authentication circuits are provided between a debug I/F circuit and a debug terminal. The authentication circuit transmits a transmission key externally at the time of activation, and authenticates based on a reception signal and the transmission key, and enables access to the debug I/F. Thus, it is possible to prevent a spurious access from the debug I/F by a third person by the authentication circuit.
