FIFORST

FIFORST:

The FIFORST bit is used to reset the internal four cell receive FIFO. When

FIFORST is set to logic zero, the FIFO operates normally. When FIFORST is set

to logic one, the FIFO is immediately emptied and ignores writes. The FIFO

remains empty and continues to ignore writes until a logic zero is written to

FIFORST.

DDSCR:

The DDSCR bit controls the descrambling of the cell payload. When DDSCR is a

logic one, cell payload descrambling is disabled. When DDSCR is a logic zero,

payload descrambling is enabled.

HECADD:

The HECADD bit controls the addition of the coset polynomial, x6+x4+x2+1, to

the HEC octet prior to comparison. When HECADD is a logic one, the

polynomial is added, and the resulting HEC is compared. When HECADD is a

logic zero, the polynomial is not added, and the unmodified HEC is compared.
