The registers found in the vendor defined PnP space take prece-
dence over any other power-down mode. You can shut down
the embedded DSP or the entire codec by writing to these
registers.

CODEC CONTROL REGISTER ARCHITECTURE
Upon Plug and Play initialization, a base address is assigned for
the Windows Sound System Compatible logical device embed-
ded in the AD1812. The AD1812 accepts both data and con-
trol information through the 16-bit interface.

PIO Data Registers
A write to or a read from the Indexed Data Register will access
the Indirect Register which is selected by the value most recently
written to the Index Address Register. The Status Register and
the PIO Data Register are always accessible directly, without in-
dexing. The 32 Indirect Registers are shown in Table XVII.
