Abstract
A semiconductor device includes a first processor configured to generate a first error check code of a first data and an audio circuitry. The audio circuitry is configured to receive the first data, receive a second data, generate a second error check code of the first data, and generate a modulation signal based on the first and second data. The first processor may determine whether the first and second error check codes are identical to each other. The first processor may control the audio circuitry to control the generation of the modulation signal based on at least the first data, in response to a determination that the first and second error check codes are identical to each other.
Claims9
A semiconductor device, comprising:
- an audio circuitry configured to
- receive a warning signal and an audio signal,
- modulate at least one of an amplitude or a frequency of the warning signal and the audio signal to generate a modulated warning signal and a modulated audio signal, and
- output the modulated warning signal and the modulated audio signal to a pad to cause the pad to output an output warning signal;
- and
- a control circuitry configured to control an operation of the audio circuitry,
- wherein the audio circuitry is configured to transmit a comparison result signal to the control circuitry based on comparing the modulated warning signal with the output warning signal.
A semiconductor device, comprising:
- a central processing circuitry configured to control an input and an output of an audio signal;
- a warning signal control circuitry configured to generate a warning signal and generate a first CRC code of the warning signal;
- and
- an output signal generation circuitry configured to generate an output signal to be output to an external device, based on the audio signal and the warning signal,
- wherein the output signal generation circuitry is configured to receive the warning signal, generate a second CRC code of the warning signal, and transmit the second CRC code to the warning signal control circuitry, and
- the warning signal control circuitry is configured to control the output signal generation circuitry to generate the output signal in response to a determination that the first CRC code and the second CRC code are identical to each other.
