8085 program to separate (or split) a byte into two nibbles

Here we will see how to split two nibbles of an 8-bit number.

Problem Statement

Write 8085 Assembly language program to split two nibbles of an 8-bit number. Number is stored at F050, we will store result at F051 and F052.

Discussion

To get the nibbles separately, at first we are taking number into B register as a copy. Now mask upper nibble to get lower nibble and store it, then take the number from B again, mask lower nibble to get upper nibble, then rotate it four times to make it lower order nibble, after that store it to another location.
