main low-pass is frozen; main high-pass is pre-charged to level on pin QGND
main low-pass is frozen; time constant of main high-pass is reduced by a
factor of 16 for bit FILTERH = 0 and by a factor of 8 for bit FILTERH = 1
main high-pass time constant is reduced by a factor of 16 for bit FILTERH = 0
and by a factor of 8 for bit FILTERH = 1; second high-pass is pre-charged
store signal amplitude (see also bit AMPCOMP in Table 5)
set status bit AMPCOMP when the actual data signal amplitude is higher than
the stored reference
store actual amplitude of the data signal as reference for later amplitude
