Big-endian e Little-endian sono due metodi differenti usati
dalle MCU e MPU per immagazzinare in memoria i dati superiori al byte.
little-endian è la memorizzazione che inizia dal byte meno significativo per finire col più significativo, è usata dagli ARM CORTEX.
big-endian è la memorizzazione che inizia dal byte più significativo per finire col meno significativo.
Big-endian e Little-endian are two different methods used by the MCU and MPU for storing data in memory for quantity more then a single byte
little-endian storage is starting from the least significant byte to finish with the most significant, is used by ARM CORTEX.
big-endian storage is starting from most significant byte to finish with the least significant.
