LCDI:
The LCDI bit is set high when there is a change in the loss of cell delineation (LCD) state.
This bit is reset immediately after a read to this register.
FOVRI:
The FOVRI bit is set high when an attempt is made to write into the FIFO when it is already
full. This bit is reset immediately after a read to this register. Continuous over-writing of the
FIFO results in only one interrupt.
UHCSI:
The UHCSI bit is set high when an uncorrected HCS error is detected. This bit is reset
immediately after a read to this register.
CHCSI:
The CHCSI bit is set high when a corrected HCS error is detected. This bit is reset
immediately after a read to this register.
OOCDI:
The OOCDI bit is set high when the RXCP enters or exits the SYNC state. The OOCDV bit
indicates whether the RXCP is in the SYNC state or not. The OOCDI bit is reset immediately
after a read to this register.
LCDV:
The LCDV bit gives the Loss of Cell Delineation state. When LCD is high, an out of cell
delineation (OCD) defect has persisted for the number of cells specified in the LCD Count
Threshold register. When LCD is low, no OCD has persisted for the number of cells specified
