Table 61 - LUT Base Address Register
Table 63 - VC Match Enable Register
Contains the 16 most significant bits of the Look-Up Table base address. These bits
represent 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.
Contains match values for each of the twelve bits in the VPI (including the GFC field).
Always reads “0000”.
