In 8085 general purpose registers are used to hold data like any other registers.
In 8085 there are six types of special registers called general purpose registers.
The general purpose registers in 8085 are B, C, D, E, H and L.
Each register can hold 8 bit data. Apart from above functions these registers can also be used to work in pairs to hold 16 bit data.
They can work in pairs such as B-C, D-E, H-L to store 16 bit data.
The H-L pair work as a memory pointer.
A memory pointer holds the address of a particular memory location. They can store 16 bit address as they work in pairs.
