Hword Reserved, should be cleared.
Hword Performance monitoring table base. User-defined offset from dual-port
RAM base.
Hword APC parameter table base address. User-defined offset from dual-port
RAM base.
Hword Free buffer pool parameter table base. User-defined offset from dual-port
RAM base.
Hword Interrupt queue parameter table base. User-defined offset from dual-port
RAM base.
— Reserved, should be cleared.
Hword UNI statistics table base. User-defined offset from dual-port RAM base.
Note that this must be set up according to Section 29.10.7, "UNI Statistics
Table>" It is not optional.
Word BD table base address extension. BD_BASE_EXT[0–7] holds the 8
most-significant bits of the Rx/Tx BD table base address.
BD_BASE_EXT[8–31] should be zero. User-defined.
Word Base address of the address compression VP table/external CAM.
User-defined.
Word Base address of the address compression VC table. User-defined.
Word Base address of the address compression VP1 table/EXT CAM1.
User-defined.
Word Base address of the address compression VC1 table. User-defined.
Hword VP mask for address compression lookup. User-defined.
Hword VCI filtering enable bits. When cells with VCI = 3, 4, 6, 7-15 are received
and the associated VCIF bit = 1 the cell is sent to the raw cell queue.
VCIF[0–2, 5] should be zero. See Section 31.10.1.2, "VCI Filtering
(VCIF)."
Hword Global mode. User-defined. See Section 31.10.1.3, "Global Mode Entry
(GMODE)."
Hword The information field associated with the last host command.
User-defined. See Section 31.14, "ATM Transmit Command."

Word Constant mask for CRC32. Initialize to 0xDEBB_20E3.
Hword AAL1 SNP protection look-up table base address. (AAL1 CES only.) The
32-byte table resides in dual-port RAM. AAL1_SNPT_BASE must be
halfword-aligned. User-defined offset from dual-port RAM base. See
Section 31.10.6, "AAL1 Sequence Number (SN) Protection Table."
