Interface Status Control
(reset = 05
hex
)
This control cell allows to enable/disable the data I/O interfaces. In addition,
the clock of the output data interface interfaces, S/PDIF and SDO, can be set
to a low-impedance mode.

In order to achieve a correct internal operating frequency of the DSP, the nom-
inal crystal frequency has to be deposited into this memory cell.
Changes at this memory address must be validated by setting bit[0] of
D0:346
