Look at the manual sections called "Using Access Registers",
which can also be found via Google.

There's an introductory section in "z/OS MVS Programming:
Assembler Services Guide", and more details in "z/OS MVS
Programming: Extended Addressability Guide".  From a
hardware architecture point of view, you can find more
about how it works in "z/Architecture Principles of
Operation".
