Part $1$: Memory access and moving data

Instruction Value after execution of instruction

LDR R$1,$const$\_$val R$1=$

LDR R$0,=$const$\_$val R$0=$

First $8$ bytes of memory starting at

address in R$0$

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

LDRH R$1,[$R$0]$ R$1=$

LDRB R$1,[$R$0]$ R$1=$

LDR R$0,=$equate$\_$val R$0=$

LDR R$1,=$const$\_$val R$1=$

STR R$0,[$R$1]$ R$0=$ R$1=$

First $8$ bytes of memory starting at

address in R$1$

MOV R$2,$R$0$ R$0=$ R$2=$

MOVS R$2,$#$0$ R$2=$

Question:

LDR R$0,=$const$\_$val has different behavior than LDR R$0,=$equate$\_$val.
