Word External transmit connection table extension base. User-defined.
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).
Hword Points to the base address of the internal RxQD table. The pointer should
be 32-byte aligned. User-defined.
Hword Performance monitoring table base. User-defined.
Hword APC parameters table base address. User-defined.
Hword Free buffer pool parameters table base. User-defined.
Hword Interrupt queue parameters table base. User-defined.
— Reserved. Should be cleared during initialization.
Hword UNI statistics table base. User-defined.
Word BD table base address extension. BD_BASE_EXT[0-7] hold the 8 most
significant bits of the RX/TxBD 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 VCI_Filtering bit = 1 the cell is sent to the raw cell
queue. VCI=3 is associated with VCI_Filtering[3], VCI=15 is associated
with VCI_Filtering[15]. VCI_Filtering[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. "
