**Refer to the following program and determine the value of Y after the program is run:**
```
.ORIG x3000
LDI R1, X
ADD R1, R1, #2
LDI R2, Y
AND R2, R2, x0
ADD R2, R1, R1
ADD R2, R1, R1
ADD R2, R1, R1
STI R2, Y
X .FILL x3200
Y .FILL x3201
.END
```
**Explanation of the program:**
- **.ORIG x3000**: Sets the starting address of the program to memory location x3000.
- **LDI R1, X**: Loads the value from the address specified in X (which is x3200) into register R1.
- **ADD R1, R1, #2**: Adds the immediate value 2 to the value in register R1.
- **LDI R2, Y**: Loads the value from the address specified in Y (which is x3201) into register R2.
- **AND R2, R2, x0**: Clears register R2 by performing an AND operation with 0.
- **ADD R2, R1, R1**: Adds the value in R1 to itself and stores the result in R2. (First ADD)
- **ADD R2, R1, R1**: Adds the value in R1 to itself again and stores the result in R2. (Second ADD)
- **ADD R2, R1, R1**: Adds the value in R1 to itself again and stores the result in R2. (Third ADD)
- **STI R2, Y**: Stores the value in R2 to the address specified in Y (which is x3201).
- **X .FILL x3200**: Defines the memory location X with the value x3200.
- **Y .FILL x3201**: Defines the memory location Y with the value x3201.
- **.END**: Indicates the end of the program.
**Step-by-step execution:**
1. **LDI R1, X**: Assuming the value at memory address x3200 is Vx, R1 now contains Vx.
2. **
