8085 is a Microprocessor which was developed by Intel in 1970s. All the instructions in this microprocessor are encoded in a single byte. Some of the instructions are followed by one or two bytes of data, which can be a memory address, an immediate operand or a port number.

In this post, we will write a program in 8085 to convert binary number to binary coded decimal(BCD).

### Algorithm

Start Read binary number(C) Clear accumulator(A) D <- 0 A <- A + 1 Adjust for BCD count If CS != 1 go to 9 D <- D + 1 C <- C - 1 if CS != 0 go to 5 Store A as lower bits Store D as upper bits Stop

### Flow Chart

### Program

LXI H, 2100H MVI D, 00H XRA A MOV C, M LOOP: ADI 01H DAA JNC SKIP INR D SKIP: DCR C JNZ LOOP MOV L, A MOV H, D SHLD 2201H RST-5

### Example

2100H: F0 2101H: 40 -> lower bits 2105H: 02 -> upper bits // output is 240
