it seems that you haven't realy understood the difference between 8 and 32 bit

your pictures are a bit wrong

in 8 bit mode you will get correctly

0x00000000 0x35

0x00000001 0x56

0x00000002 0xF6

but in 32 bit mode there is no adr at 0x00000001 as the lowest 2 bits are always 0

in 32 bit you will have

0x00000000 0x3556....

but the next possible adr is

0x00000004 0x.....

in 16 bit mode you will memory adr.

0x00000000 0x????

0x00000002 0x????

0x00000004 0x????

0x00000006 0x????

it didn't look after bigendian stuff here
