I'm a little confused with the Register Pointer. I think I understand that the Upper Nibble points to the register group (contains 16 registers (bytes)). And the Lower Nibble points to the bank (contains 16 groups). Then, how do you access the specific registers? Just by using Rn (n being 0 to 15)? Like, you would specify the bank and the group and then you would use (for example) R5 to get the 6th register.

If I'm wrong can someone set me in the direction? Also, can somebody include code (Assembly) on how to do this?

Thanks! I appreciate.

Cheers,
Sebastian
