CELL_SIZE
00
Cell Size, Three bits to set cell size.
“000” - Cell size is 75 bytes,
“001” - Cell size is 79 bytes,
“010” - Cell size is 83 bytes,
“011” - Cell size is 91 bytes
These are the only supported cell sizes.
Cell

RX_FIFO_MIN
Set Minimum threshold value for alignment
FIFO in SONET mode. When the read address
for the FIFO is below this value at the time when
write address is zero, it indicates that the FIFO
is near overow. This event will go high only
once during a frame when a framing byte has
been detected by the aligner. The default
threshold value is “00000”.

0
TX_DISABLE_ON_RDI
00
Transmitter Disable on RDI (Detection), If
TX_DISABLE_ON_RDI = 1 - No cell data is
transmitted on a link in which a RDI has been
detected by the corresponding link’s receiver. If
this bit is set to 0, cell data will be transmitted on
a link irrespective of detection of a RDI.

SCHAR_ENA
SCHAR_ENA = 1 enables SERDES character-
ization of SERDES B. Refer to section

SCHAR_TXSEL
SCHAR_TXSEL =1 is a Select Tx option which
will cause chip ports to directly control the SER-
DES low-speed transmit ports of one of the
channels selected by SCHAR_CHAN
