28 / 126 page  Product overview STLUX 28/126 DocID027870 Rev 1 Status flags: – Transmitter/receiver mode flag – End of byte transmission flag –I2C busy flag Error flags: – Arbitration lost condition for master mode – Acknowledgment failure after address/ data transmission – Detection of misplaced start or stop condition – Overrun/underrun if clock stretching is disabled Interrupt sources: – Communication interrupt – Error condition interrupt – Wakeup from Halt interrupt Wakeup capability: – MCU wakes up from low power mode on address detection in slave mode. 5.8 Analog-to-digital converter (ADC) The STLUX family includes a 10-bit successive approximation ADC with 8 multiplexed input channels. The analog input signal can be amplified before conversion by a selectable gain of 1 or 4(a) times. The analog-to-digital converter can operate either in single or in continuous/circular modes. The ADC unit has the following main features: 8/6 ADC input channel(b) 10-bit resolution Single and continuous conversion mode Independent or fixed channel gain value x1 or x4 to extend dynamic range and resolution to 12-bit equivalent(a) Interrupt events: – EOC interrupt asserted on end of conversion cycle – EOS interrupt asserted on end of conversion sequences – SEQ_FULL_EN interrupt assert on sequencer buffer full ADC input voltage range dependent on selected gain value(b) Selectable conversion data alignment Individual registers for up to 8 successive conversions. a. The gain x4 is available only on the STLUX385A. b. The number of ADC input channels depends of the STLUX device part number. |
