31-23

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.

0x4C

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).

0x5E

Hword

Reserved, should be cleared during initialization.

0x60

PMT_BASE

Hword

Performance monitoring table base. User-defined.

0x62

APCP_BASE

Hword

APC parameters table base address. User-defined.

0x64

FBT_BASE

Hword

Free buffer pool parameters table base. User-defined.

0x66

INTT_BASE

Hword

Interrupt queue parameters table base. User-defined.

0x5E

Reserved, should be cleared during initialization.

0x6A

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

VPT_BASE /
EXT_CAM_BASE

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.
