Selects frame reference input and the sampling of the selected reference for frame alignment. T4 timing gener-
ator does not support frame phase alignment.
Frame reference input selection:
Selects any one from the three external sync inputs as frame reference for Ref1~Ref5 individually. External
sync inputs can take frequency of 2kHz or 8kHz and this frequency is auto-detectable. When none of frame ref-
erence inputs is used, set 0 to select its own frame pulse output of CLK8K as frame reference.

Frame phase alignment and edge selection:
Selects either frame phase arbitrary mode or frame phase align mode. Selects the sampling edge on the
selected reference input in phase align mode. If phase arbitrary mode is selected, any selection of frame refer-
ence will be dismissed.
