Address: 4002 (Hex)
Label: UNCB
Reset Value: 0000 (Hex)
Note: The contents of this register are used to determine how many bits of the cell header are used to form the look-up table addresses.
The user selects up to 16 of the bits of the GFC/VPI and VCI fields to be used for the look-up table search. A minimum of 4 bits (from the
VCI) and a maximum of 16 bits (all from the VCI or from a combination of both the VCI and VPI) of the header must be used for searches.

Always reads “0000_00”.
Contains the 16 most significant bits of the Look-Up Table base address. These bits repre-
sent byte address bits<20:5> of the external memory.
If N+M is greater than 4, bits<(N+M):5> of the Look-Up Table base address should be
set to 0. (For example, if N+M=7, bits<7:5> should be set to “000”)
Contains match values for each of the bits in the VCI.
Each bit, when set, enables the comparison of a cell’s VCI and the corresponding
VC_MATCH bit. If a bit in this register is not set, the corresponding bit in the received cell
VCI is considered valid, regardless of the setting in the VC_MATCH field.
