Abstract
A semiconductor integrated circuit, operable in a normal mode and a test mode, includes a demodulator, a demodulated signal processing section, a header analysis section, a payload processing section, and a control section. The demodulator demodulates a modulated wireless signal including a synchronization pattern, header, and payload, to generate a demodulated signal. The demodulated signal processing section detects the synchronization pattern from the demodulated signal, generates a synchronization detection signal synchronized to the synchronization pattern, and converts the demodulated signal into a received bit sequence. The header analysis section extracts and analyzes the header to obtain the number of bits of the payload. The payload processing section processes the payload. The control section disables the demodulator when processing of the number of bits in the payload is completed in the normal mode, and disables the demodulator synchronously with a signal indicating the end of a test in the test mode.
