Explanation / Answer

Addr : hex binary instr/data

005c18 : 4034 0100 0000 0011 0100 mov.w #0x5C0C, R4

005c1a : 5C0C 0101 1100 0000 1100 #0x5c0c

005c1c : 4345 0100 0011 0100 0101 mov.b ,R5

005c1e : 4476 0100 0100 0111 0110 mov.b,R7

005c20 : 9306 1001 0011 0000 0110 cmp

005c22 : 2405 0010 0100 0000 0101

005c24 : 9076 1001 0000 0111 0110 cmp
