0x44
UDC_TMP_BASE
Hword
UDC mode only. Points to a total of 32 bytes reserved dual-port RAM
area used by the CP. Should be 64-byte aligned. User-defined.
(recommended address space: 3000h-4000h or b000h-c000h)
0x46
INT_RCT_BASE
Hword
Internal receive connection table base. User-defined.
0x48
INT_TCT_BASE
Hword
Internal transmit connection table base. User-defined.
0x4A
INT_TCTE_BASE
Hword
Internal transmit connection table extension base. User-defined. Note
that the TCT extension is not needed in AAL1 CES and that the AAL1
CES microcode uses this Hword to point to a CAS routing table.

Word
Reserved, should be cleared during initialization.
0x50
EXT_RCT_BASE
Word
External receive connection table base. User-defined.
0x54
EXT_TCT_BASE
Word
External transmit connection table base. User-defined.
0x58
EXT_TCTE_BASE
Word
External transmit connection table extension base. User-defined. Note
that the TCT extension is not needed in AAL1 CES and that the AAL1
CES microcode uses this Hword to point to a CAS routing table.
0x5C
UEAD_OFFSET
Hword
User-defined cells mode only. The offset of the UEAD entry in the UDC
extra header. Should be an even address. If RCT[BO]=01
UEAD_OFFSET should be in little-endian format. For example if UEAD
entry is the first half word of the extra header in external memory,
UEAD_OFFSET should be set to 2 (second half word entry in internal
RAM).

UNI_STATT_BASE
Hword
UNI statistics table base. User-defined.
0x6C
BD_BASE_EXT
Word
BD table base address extension. BD_BASE_EXT[0–7] holds the 8 left
bits of the Rx/Tx BD table base address. BD_BASE_EXT[8–31] should
be zero. User-defined.
0x70

Word
Base address of the address compression VP table/external CAM.
User-defined.
0x74
VCT_BASE
Word
Base address of the address compression VC table. User-defined.
0x78
VPT1_BASE /
EXT_CAM1_BASE
Word
Base address of the address compression VP1 table/EXT CAM1.
User-defined.
0x7C
VCT1_BASE
Word
Base address of the address compression VC1 table. User-defined.
0x80
VP_MASK
Hword
VP mask for address compression lookup. User-defined.
