Hi All. I wish to ask anyone with knowledge on PIC16F84A processor to help me program a PIC16F84A to multiplexing two seven segment displays. The displays shall be displaying the content of a processor register. The number shall be between 00 - to - 99.

I will greatly appreciate if it could programmed in Assembly Language.
