Bit 7: Committed Information Rate Enable (CIRE). Set this bit to 1 to enable the Committed Information Rate
Controller feature.
Bits 6 to 0: Committed Information Rate (CIR6 to CIR0). These bits provide the value for the committed
information rate. The value is multiplied by 500kbps 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 52Mbps 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.
