Register XR2 configures the data-upstream command/indication channel.
Bit
Upstream Update Interval N
To restrict the rate of upstream C/I-bit changes, deglitching (persistence checking) of the
status information from the SLIC may be applied. New status information will be
transmitted upstream, after it has been stable for N milliseconds. N is programmable in
the range of 1 to 15 ms in steps of 1 ms, with N = 0 the deglitching is disabled.

Detector Select Sampling Interval T
SLICs with multiplexed loop- and ground-key-status, which have a single status output
pin for carrying the loop- and ground-key-status information, need a special detector
select input.
