/**
 * @brief	This is the device handler class for the SUS sensor based on the MAX1227 ADC.
 *
 * @details
 * Datasheet of MAX1227: https://datasheets.maximintegrated.com/en/ds/MAX1227-MAX1231.pdf
 * Details about the SUS electronic can be found at
 * https://egit.irs.uni-stuttgart.de/eive/eive_dokumente/src/branch/master/400_Raumsegment/443_SunSensorDocumentation/release
 *
 * @note    When adding a SusHandler to the polling sequence table make sure to add a slot with
 *          the executionStep FIRST_WRITE. Otherwise the communication sequence will never be
 *          started.
