Wide Atomic Register
^^^^^^^^^^^^^^^^^^^^
Without write-buffering, it is impossible to update the state of a 64-bit
register using a 32-bit CPU interface in a single clock-cycle.
In this example, it still requires two write-cycles to update the register, but

Atomic Group of Registers
^^^^^^^^^^^^^^^^^^^^^^^^^
Perhaps you have a group of registers that need their state to be updated
atomically. Using the ``wbuffer_trigger`` property, you can define which
register write operation triggers the group to be updated.
