1141 / 1386 page  ATM AAL2 MPC8280 PowerQUICC II Family Reference Manual, Rev. 1 Freescale Semiconductor 33-35 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 RxQD_Base_Int Hword Points to the base address of the internal RxQD table. The pointer should be 32-byte aligned. User-defined. 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. 0x68 — — 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] hold the 8 most significant bits of the RX/TxBD 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. 0x82 VCI_Filtering 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).” 0x84 GMODE Hword Global mode. User-defined. See Section 31.10.1.3, “Global Mode Entry (GMODE) .” 0x86 COMM_INFO Hword The information field associated with the last host command. User-defined. See Section 31.14, “ATM Transmit Command. “ 0x88 Hword 0x8A Hword 0x8C — Word Reserved. Should be cleared during initialization. 0x90 CRC32_PRES Word Preset for CRC32. Initialize to 0xFFFFFFFF. 0x94 CRC32_MASK Word Constant mask for CRC32. Initialize to 0xDEBB20E3. Table 33-13. AAL2 Parameter RAM (continued) Offset Name Width Description |
