When CnC is enabled and it's locked, it monitors the ratio between
the interferer and the desired power in dB.
Example 1: CRM==+02 (interferer > desired)
Example 2: CRM=LT10 (less than –11 dB)
Example 3: CRM=GT10(greater than +11 dB)
Example 4: CRM=99.9 (not locked or CnC not enabled)

When CnC is enabled and it's locked, it monitors the delay of the
interferer in microseconds.
Example 1: CDM=229,500 (229.5 ms)
Example 2: CDM=999,999 (not locked or CnC not enabled)
6 bytes
Query only
When CnC is enabled, an estimated frequency offset between
desired and interferer will be calculated.
Unit is in kilohertz ( kHz).
Example 1: CFM=+001.0 (1 kHz)
Example 2: CFM=9999.9 (not locked or CnC not enabled)
