Explanation / Answer

Starting address is 0x2000

64 bit Value : 0x 20 12 5b 09 00 cb 7a 01

LITTLE ENDIAN

0x2000 : 20
0x2001 : 12
0x2002 : 5b
0x2003 : 09
0x2004 : 00
0x2005 : cb
0x2006 : 7a
0x2007 : 01

BIG ENDIAN

0x2000 : 01
0x2001 : 7a
0x2002 : cb
0x2003 : 00
0x2004 : 09
0x2005 : 5b
0x2006 : 12
0x2007 : 20

Big Endian
The MSB of the data is placed at the byte with the lowest address.

Little Endian

The LSB of the data is placed at the byte with the lowest address.
