bucket_id_<n>
Every input has its own Leaky Bucket used for
activity monitoring. There are four possible
configurations for each Leaky Bucket- see Reg. 50
to Reg. 5F. This 2-bit field selects the configuration
used for input I<n>.
reference_source_frequency_<n>
Programs the frequency of the reference source
connected to input I<n>. If divn_<n> is set, then
this value should be set to 0000 (8 kHz).
