-The Imagination Technologies SPDIF Input controller contains the following
-controls:
-
-name='IEC958 Capture Mask',index=0
-
-This control returns a mask that shows which of the IEC958 status bits
-can be read using the 'IEC958 Capture Default' control.
-
-name='IEC958 Capture Default',index=0
-
-This control returns the status bits contained within the SPDIF stream that
-is being received. The 'IEC958 Capture Mask' shows which bits can be read
-from this control.
-
-name='SPDIF In Multi Frequency Acquire',index=0
-name='SPDIF In Multi Frequency Acquire',index=1
-name='SPDIF In Multi Frequency Acquire',index=2
-name='SPDIF In Multi Frequency Acquire',index=3
-
-This control is used to attempt acquisition of up to four different sample
-rates. The active rate can be obtained by reading the 'SPDIF In Lock Frequency'
-control.
-
-When the value of this control is set to {0,0,0,0}, the rate given to hw_params
-will determine the single rate the block will capture. Else, the rate given to
-hw_params will be ignored, and the block will attempt capture for each of the
-four sample rates set here.
-
-If less than four rates are required, the same rate can be specified more than
-once
-
-name='SPDIF In Lock Frequency',index=0
-
-This control returns the active capture rate, or 0 if a lock has not been
-acquired
-
-name='SPDIF In Lock TRK',index=0
-
-This control is used to modify the locking/jitter rejection characteristics
-of the block. Larger values increase the locking range, but reduce jitter
-rejection.
-
-name='SPDIF In Lock Acquire Threshold',index=0
-
-This control is used to change the threshold at which a lock is acquired.
-
-name='SPDIF In Lock Release Threshold',index=0
-
-This control is used to change the threshold at which a lock is released.
