Register Name:
LI.CIR
Register Description:
Committed Information Rate
Register Address:

Name CIRE CIR6 CIR5 CIR4 CIR3 CIR2 CIR1 CIR0
Default 0 0 0 0 0 0 0 1
Bit 7: Committed Information Rate Enable (CIRE) Set this bit to 1 to enable the Committed Information Rate
Controller feature.
Bits 0 – 6: Committed Information Rate (CIR0-6) These bits provide the value for the committed information rate.
The value is multiplied by 500kbit/s to get the CIR value. The user must ensure that the CIR value is less than or
equal to the maximum Serial Interface transmit rate. The valid range is from 1 to 104. Any values outside this range
will result in unpredictable behavior. Note that a value of 104 translates to a 52Mbit/s line rate. Hence if the CIR is
above the line rate, the rate is not restricted by the CIR. For instance - if using a T1 line and the CIR is
programmed with a value of 104, it has no effect in restricting the rate.
