The registers in a microcontroller contain the following values: r3: 0x00000000 ro: 0x000010f4 r1: 0x0000000e r2: 0x00000000 The following data is also stored in memory: Address Data 0x000010fc Ox0000369C Ox000010f8 Ox00002468 0x00001054 Ox0000d00d Ox000010fo Ox00001111 Finally, the following code is executed: mov r2, #20 idr r3, [re, #4] add ri, r3 idr r3, [re, #-4]! add r2, r3 str r2, [ro], #8 What are the contents of the registers and memory after this code is executed? Registers: ro: r1: r2: r3: Memory: Address Data Ox000010fc Ox000010f8 Ox000010f4 Ox0000100
