The subport address of a cell containing an invalid cell header.
Value used to validate cells on the Rx UTOPIA interface.
Value used to validate cells on the Rx UTOPIA interface.
Value used to validate cells on the Rx UTOPIA interface.
Cell header used for In-Stream™ programming cells.
Cell header used for In-Stream™ programming cells.
Cell header used for In-Stream™ programming cells.
Cell header used for In-Stream™ programming cells.
Subport address used to filter In-Stream™ programming cells.
Programs how many bits will be used for subport addressing in the transmit
direction.
New value used to replace subport address in outgoing cells. This value will
only be used if the Replace Subport bit of the Modify Tx Subport register is
set to a one.
"Indicates whether or not to replace the subport address in transmit cells.
"0" do not replace the subport address, "1" replace the subport address with
the value in the New Subport bits of the Modify Tx Subport register."
Indicates what byte of the transmit cell header the subport starts in. The
subport address can cross the byte boundary.
Indicates what bit of the byte defined by the Tx Byte Location bits of the Tx
Subport Position register the MSB of the transmit subport address starts.
The subport address can cross the byte boundary.
