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 500 kbps 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 52 Mbps 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.
