8085 program to unpack 16-bit BCD, and store consecutive locations

Here we will see we can take 16-bit BCD data from memory and unpack it, then store into memory using 8085.

Problem Statement

Write 8085 program to take 16-bit BCD number from memory then store each digit by unpacking into different locations.

Discussion

To solve this problem, we will create one subroutine, that can unpack 1-byte BCD number and store into memory, then we will use that subroutine for two times to store 16-bit data. The subroutine will cut the numbers by masking upper nibble and lower nibble, and store into memory.

Input

1234 in the DE register pair
