// If the readed data comes in the range of uint8_t we should use Part I functions.
// The function to convert the array of uint16_t containing uint8_t values into other
// types are developed in the first part of this class.
//
// At somepoint in SCADA-Mission software, there must be some conversions from
// uint16_t arrays to other types. This types needs to separate the uint16_t into
// two uint8_t before the conversions. This functions comes into the second part of the class.
// This part haven't been used in the DCU code yet. But since it is developed well, we let it
// be for the future needs.
