5. When an 8-bit or 16-bit data is loaded from the data memory into a 32-bit register, LDRSB (load register with signed byte) LDRSH loads a signed byte and LDRB LDRSH (load register with signed halfword) and LDRH (load register with whether sign extension or zero extension is performed depends on the data's sign (load register with byte) for an unsigned byte. halfword) read load a 16-bit signed and unsigned number from memory into a register, respectively What is the value in register ri in the following instructions if re 0x20008000? Assume the system is little endian. (1) LDRSB r1, [re] (2) LDRSH r1, [re] (3) LDRB r1, [re] (4) LDRH r1, [re] Memory address 0x20008002 0x20008001 0x20008000 0x20007FFF 0x20007FFE Data 0xA1 0xB2 0xC3 0xD4 0xE5
