Register 0C1H: RW8D Interrupt Status
This register reports interrupt status due to change of character alignment, change of frame
alignment, detection of line code violations, and FIFO overrun or underrun events in the RW8D.

The out-of-character-alignment interrupt status bit (OCAI) reports and acknowledges change
of character alignment state interrupts. Interrupts are generated when the character alignment
block changes state to the out-of-character-alignment state or to the in-character-alignment
state. OCAI is set high when change of state occurs. When the interrupt is masked by the
OCAE bit the OCAI remains valid and may be polled to detect change of frame alignment
events.
The out-of-frame-alignment interrupt status bit (OFAI) reports and acknowledges change of
frame alignment state interrupts. Interrupts are generated when the frame alignment block
changes state to the out-of-frame-alignment state or to the in-frame-alignment state. OFAI is
set high when change of state. When the interrupt is masked by the OFAE bit the OFAI
remains valid and may be polled to detect change of frame alignment events.
