Problem statement:

問題陳述：

To mask lower and higher nibble of 8-bit number using 8085 Microprocessor.

使用8085微處理器掩蓋8位數字的較低和較高半字節。

Algorithm:

算法：

1. Load the content of accumulator A with an 8bit number.

   用8位數字加載累加器A的內容。

2. Copy the content of accumulator to the register B.

   將累加器的內容復制到寄存器B中。

3. Perform AND operation on the content of accumulator with 0F.

   用0F對累加器的內容執行AND操作。

4. Store the result in a memory location.

   將結果存儲在存儲位置中。

5. Copy the content of register B to the register accumulator.

   將寄存器B的內容復制到寄存器累加器。

6. Perform AND operation on the content of accumulator with F0.

   用F0對累加器的內容執行AND操作。

7. Perform RLC operation 4 times.

   進行4次RLC操作。

8. Terminate the program.

   終止程序。

Program:

程序：

	LDA     2051
MOV     B, A
ANI     0F
STA     2052
MOV     A, B
ANI     F0
RLC
RLC
RLC
RLC
STA     2053
HLT

Observation:

觀察：

    INPUT: 
2051:16
OUTPUT: 
2052:06
2053:01

Hence, we successfully masked the lower and higher nibble of 8-bit number.

因此，我們成功地掩蓋了8位數字的較低和較高的半字節 。
