View Ref-FileOffset Registers (Nn) N0-N7

    The eight 16-bit offset registers, N0-N7, can contain offset values used
to increment/decrement address registers in address register update
calculations or can be used for 16-bit general-purpose storage. For example,
the contents of an offset register can be used to step through a table at
some rate (e.g., five locations per step for waveform generation), or the
contents can specify the offset into a table or the base of the table for
indexed addressing. Each address register, Rn, has its own offset
register, Nn, associated with it. Each offset register is preset to $FFFF
during a processor reset.
