LCVI
FUOI
The line code violation event interrupt status bit (LCVI) reports and acknowledges line code
violation interrupts. Interrupts are generated when the character alignment block detects a
line code violation in the incoming data stream. LCVI is set high when a line code violation
event is detected. When the interrupt is masked by the LCVE bit the LCVI remains valid and
may be polled to detect change of frame alignment events.
The FIFO underrun/overrun event interrupt status bit (FUOI) reports and acknowledges the
FIFO underrun/overrun interrupts. Interrupts are generated when the character alignment
block detects a that the read and write pointers are within one byte of each other. FUOI is set
high when this event is detected. When the interrupt is masked by the FUOE bit the FUOI
remains valid and may be polled to detect underrun/overrun events.
