The registers in a microcontroller contain the following values: ro: Ox00002000 r1: 0x00000004 r2: 0x00000000 r3: Ox00000000 The following data is also stored in memory: Address Data Ox00002008 Ox00003690 Ox00002004 Ox00002468 Ox00002000 Ox00000040 Ox00001FFC Ox00001111 Finally, the following code is executed: mov r2, #4 Ldr r3, [ro] sub ro, ro, r1 add ri, r3 ldr r3, [ro] add r2, r3 str r2, [ro] What are the contents of the registers and memory after this code is executed? Registers: ro: r1: r2: r3: : Memory: Address Data Ox00002008 Ox00002004 Ox00002000 Ox00001FFC
