This register is used to indirectly read and write the ingress rate metering/color table registers. A write
to this address performs the specified access.

For a read access, the Operation Pending bit in the

CIR Address
These bits select one of the 24 Committed Information Rate registers.

When Rate Mode is set to Source Port & Priority in the 

, the first 

set of 8 registers (CIR addresses 0-7) are for to Port 0, the second set of 8 
registers (CIR addresses 8-15) are for Port 1, and the third set of registers 
(CIR addresses 16-23) are for Port 2. Priority 0 is the lower register of each 
set (e.g. 0, 8, and 16).

When Rate Mode is set to Source Port Only, the first register (CIR address 
0) is for Port 0, the second register (CIR address 1) is for Port 1, and the 
third register (CIR address 2) is for Port 2.

When Rate Mode is set to Priority Only, the first register (CIR address 0) is 
for priority 0, the second register (CIR address 1) is for priority 1, and so 
forth up to priority 23.

Values outside of the valid range may cause unexpected results.
