MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -ARM (and intel) processors are Little Endian-which means that sometimes the 4 bytes of a word in memory will look like they are backwards.

Detailed explanation-2: -Big-endian is an order in which the “big end” (most significant value in the sequence) is stored first, at the lowest storage address. Little-endian is an order in which the “little end” (least significant value in the sequence) is stored first.

Detailed explanation-3: -If the hardware is built so that the lowest, least significant byte of a multi-byte scalar is stored “first", at the lowest memory address, then the hardware is said to be “little-endian"; the “little” end of the integer gets stored first, and the next bytes get stored in higher (increasing) memory locations.

Detailed explanation-4: -What Does Little-Endian Mean? The little-endian convention is a type of addressing that refers to the order of data stored in memory. In this convention, the least significant bit (or “littlest” end) is first stored at address 0, and subsequent bits are stored incrementally.
