FIFORST:  
The FIFORST bit is used to reset all the logical channel FIFOs for a link.  
When FIFORST is set to logic 0, the FIFO channels operate normally. When  
FIFORST is set to logic 1, all the FIFOs are immediately emptied and ignore  
writes. The FIFOs remain empty and continue to ignore writes until logic 0 is  
written to FIFORST. This results in a continuous stream of stuff cells on  
TXDn+/-.  
If a user cell is currently being sent over the LVDS link it will likely be  
corrupted by the reset. If the header portion of the cell has been sent then  
this corruption will not be detected at the receiver if header error detection is  
enabled. However it will likely be detected if cell error detection is enabled.  
See Transmit High-Speed Serial Configuration Register, CELLCRC bit, and  
Received High-Speed Serial Configuration Register, CELLCRC bit for details.  
FOVRE:  
The FOVRE bit enables the assertion of the INTB output due to a FIFO  
overrun error condition. When FOVRE and the Master Interrupt Enable bit of  
the Master Configuration register are set to logic 1, the interrupt is enabled.
