Sorry to confuse you.  I meant Register but my traitorous fingers typed DFF.

The PC is similar to the Bit in construction, except that Register replaces the DFF. The combinatorial logic for Bit switches between reloading the DFF output or the input value depending on load.
The PC's combinatorial logic works similarly, but as you have identified, there are more choices.

If you want more explicit help, you can contact me directly via email (More>Reply to author).
