HW_SPDIF_STAT

This bit is set by hardware if the FIFO overflows during SPDIF transmission. Reset this bit by writing a one
to the SCT clear address space and not by a general write.
Set this bit to one to enable a SPDIF interrupt request on FIFO overflow or underflow status conditions.
Setting this bit to one causes the SPDIF to begin converting data. The actual conversion will begin when
the SPDIF FIFO is filled (4 or 8 words written, depending upon sample word format, i.e., 16 or 32 bits).
