8.7.8.14
PLL reset
A 1-bit value to reset the PLL. This is the bit which is set in
the initialisation string. When this bit is asserted, the PLL
will be reset and the output clock of the PLL will be forced
to its lowest value, which is in the area of a few MHz.

EADABLE REGISTERS
8.7.9.1
Mute status
A 1-bit value indicating whether the interpolator is muting
or not muting.

Interpolator mute status
8.7.9.2
PLL lock detection
A 1-bit value indicating that the clock regeneration is
locked.

PLL lock indication
8.7.9.3
SPDIF lock detection
A 1-bit value indicating the IEC 958 decoder is locked and
is decoding correct data.

SPDIF lock detection
8.7.9.4
Audio sample frequency detection
A 2-bit value indicating the audio sample frequency of the
IEC 958 input signal.

Audio sample frequency detection
8.7.9.5
PCM detection
A 1-bit value which indicates whether the IEC 958 input
contains PCM audio data or other binary data.

Two channel PCM input detection
8.7.9.6
Pre-emphasis detection
A 1-bit value which indicates whether the pre-emphasis bit
was set on the IEC 958 input signal or not set.

Pre-emphasis detection
8.7.9.7
Clock accuracy detection
A 2-bit value indicating the timing accuracy of the IEC 958
input signal is conforming to the IEC 958 specification.
