The behavior of the SPDIF module during or after a FIFO underflow is programmable. On
detection of an underflow event, the SPDIF module sends the current sample for four frames
before muting (sending zeros) the data stream based on the configuration of
HW_SPDIF_FRAMECTRL_AUTO_MUTE. The final validity unit embedded within each
frame dictates whether the receiver processes the data within that frame.
HW_SPDIF_FRAMECTRL determines the behavior of this bit.
