Abstract
An integrated circuit ( ) comprises a microprocessor ( ), an ADC ( ) and a serial interface ( ) for communicating the integrated circuit with an external device. An analogue input port ( ) is provided for inputting analogue signals to the ADC ( ). A switch circuit ( ) is provided for selectively and alternately configuring the integrated circuit ( ) to operate in a first mode and in a second mode. In the first mode the serial interface ( ) communicates with the microprocessor ( ) through the switch circuit ( ), and in the second mode the serial interface ( ) communicates with the ADC ( ) through the switch circuit ( ). In the second mode conversion results are transferred from the ADC ( ) through the switch circuit ( ) to the serial interface ( ) independently of the microprocessor ( ) for transmission therefrom to an external device. In the first mode the ADC ( ) is operable under the control of the microprocessor ( ).
