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. If WCIMODE is set to logic 1, only over-writing with a ‘1’ clears this bit. If
WCIMODE is set to logic 0, then a read of this register automatically clears the bit.
