This register is used in conjunction with 0x819 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 0x818
and 0x819 are an indirect register pair in that a address is selected using register 0x818 and the configuration for
that address is programmed using register 0x819.

This register contains the 8 lsbs of the payload bandwidth for the specific port of the Rx Timing
clock synthesizer. The contents of this register are multiplied by 8kbps and the Rate Multiplier in
order to obtain the bandwidth.

This register contains the msb of the payload bandwidth for the specific port of the Rx Timing
clock synthesizer. The contents of this register are multiplied by 2048kbps and the Rate
Multiplier in order to obtain the bandwidth.
0 = the value in bits 5–0 enables ATM address –> IMA internal channel translations
1 = the value in bits 5–0 enables IMA internal channel –> ATM address translations

For Type 0, this field contains the ATM Side UTOPIA address.
For Type 1, this field contains the IMA internal channel address.
Range 0x00–0x1F: Receive Port
Range 0x20–0x3F: IMA Group
0 = Multiply rate by 1 (typically used by link rates < 3.072 Mbps)
1 = Multiply rate by 2 (typically used by 3.072 < link rates < 6.144 Mbps)
2 = Multiply rate by 4 (typically used by link rates > 6.144 Mbps)
3 = Not defined.
