LSI communication device with automatic test capability

摘要

A communication LSI device includes a state machine section and a test control section. The state machine section carries out a configuration operation in an idle state in response to a first reset signal. The state machine section changes to the idle state after completion of the configuration operation. The state machine section outputs a flag signal after a predetermined time since the state machine section changes to the idle state. The test control section outputs one the first reset signal to the state machine section in a test mode in response to the flag signal or a second reset signal externally supplied.
