Reverse engineer the following AVR machine code given in hexidecimal format: 05E214E321E3010F0000020F00000093000 30C940900
Hint: The only instructions included are ADD, JMP, LDI, NOP, and STS.
(a) Convert the little-endian ordered machine code above into a big-endian ordered binary list of instructions. Note that the AVR uses little-endian addressing (with the least significant byte before the most significant byte) so the executable string above is byte-addressed from left to right beginning with the byte 0x05 stored at address 0x0000. To help make your solution readable, please put each binary instruction on a separate line beginning at address 0, and put a space between each nibble. Your binary solution should be given in big-endian order (that is, the most significant byte should be on the left, and the least on the right).
(b) Disassemble the binary instructions back into equivalent AVR assembly language. Remember that the binary instructions given in the documentation are given in big-endian order. You may make up your own labels if necessary.

Code Given:
a)
Address: Hex Code | Binary Code
0x0000 : E205 | 1110 0010 0000 0101
0x0001 : E314 | 1110 0011 0001 0100

b)
LDI R16, 0x25
LDI R17, 0x34

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.
