Please answer all parts according to the example $1$ has been answered. What will be the change to the content of memory or registers after the instruction is executed?

Before each instruction is executed, the initial content of memory and processor registers is shown in

the figure below. Please note that, the instructions are executed individually. The execution of each

instruction does not depend on the results of other instructions.

LDR R$0,[$R$1]$

Ans: $1.$ indirect mode

$EA=[R1]=0x0000\mathrm{.}1010$

After execution, the content of $R0$ will be $0x0000\mathrm{.}0055.$ There will be no change to

the memory or other registers. STR R$1,[$R$1]$

LDR R$3,[$R$1,$# $-12]$

STR R$0,[$R$2,$ #$12]!$

STR R$3,[$R$1,$ R$4,$ LSR#$1]$

LDR R$0,[$R$1],-$R$3,$ LSL#$3$
