16位的数字高字节和低字节

Problem statement:

问题陈述：

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

使用8085微处理器掩盖8位数字的较低和较高半字节。

Algorithm:

算法：

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

   用8位数字加载累加器A的内容。

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

   将累加器的内容复制到寄存器B中。

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

   用0F对累加器的内容执行AND操作。

4. Store the result in a memory location.

   将结果存储在存储位置中。

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

   将寄存器B的内容复制到寄存器累加器。

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

   用F0对累加器的内容执行AND操作。

7. Perform RLC operation 4 times.

   进行4次RLC操作。

8. Terminate the program.

   终止程序。

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:

观察：

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

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

因此，我们成功地掩盖了8位数字的较低和较高的半字节 。
