OBCIFRST  
CALEVEL0  
If CALEVEL0 is logic 1, BO_CLAV is deasserted after the last word of the FIFO is  
transferrred (i.e. the FIFO is empty). If CALEVEL0 is logic 0, then BO_CLAV is deasserted  
4 words before the end of the last cell to indicate that the Output BCIF cannot transfer  
another cell.  
OBCIFRST  
The OBCIFRST bit is used to reset the 16-cell Output Backwards Cell Interface FIFO. When  
OBCIFRST is set to logic zero, the FIFO operates normally. When OBCIFRST is set to logic  
one, the FIFO is immediately emptied and ignores reads and writes. The FIFO remains  
empty and continues to ignore reads and writes until a logic zero is written to OBCIFRST.  
N.B. This FIFO must be reset at startup.  
OBCIF_EVEN_PRTY  
When this bit is logic 1, the BO_PAR pin completes even parity for the BO_DAT[15:0] bus.  
When it is logic 0, the BO_PAR pin completes odd parity for the BO_DAT[15:0] bus.  
Reserved  
The reserved bits must be programmed to logic 0 for correct operation.
