Suppose ro = 0x20008000, and the memory layout is as follows: Address Data 0x20008007 OxAB Ox20008006 OCD 0x20008005 0x23 0x20008004 OxFF Ox20008003 Ox12 0x20008002 0x23 Ox20008001 OxBC 0x20008000 Ox1A Suppose the system is set as little endian. What are the values of r1 and ro if the following instructions are executed separately (all commands run individually, i.e., all registers and memory values are reset to the initial values and are not affected by the other instructions)? Use only capital letters when writing the hex values below. LDR r1,[ro, #4 ] -> rO = Ox ,r1 = Ox LDR r1, [ro], #4 -> rO = Ox ,r1 = Ox LDR r1, [ro, #4 ]! -> rO = Ox r1 = Ox
