0x41B—IMA_TX_TRANS_TABLE (IMA Transmit Translation Table Address)
Translation Type
ATM Utopia Address
Internal IMA Channel For Type 1, this field contains the IMA internal channel address.
This register is used in conjunction with 0x41C for configure the translation between
the ATM side Utopia addresses and the internal channels (bypass ports and IMA
groups) associated with the IMA core. Register 0x41B and 0x41C are an indirect
register pair in that a address is selected using register 0x41B and the configuration
for that address is programmed using register 0x41C.
