(Excursion) Limit Count.
The SINC_LEVEL0.LCNT bits specify the number (count) of output excursions be-
yond the amplitude specified for group 0 secondary filters. The number of excursions
greater than specified by registers SINC_LIMIT3, SINC_LIMIT2,
SINC_LIMIT2, and
responding MAX or MIN bit in the
1 to 8. If the count is greater than SINC_LEVEL0.LWIN, the bit fields behavior is as
it is equal to SINC_LEVEL0.LWIN. See SINC_LEVEL0.LWIN for details. The
valid count must be one less than a desired count:
=000 require one excursion above the amplitude limit
=111 require eight excursions above the amplitude limit.
(Excursion) Limit Window.
The SINC_LEVEL0.LWIN bits specify the window size for excursion checking for
group 0 secondary filters. The window size is the number of the most recent outputs
to be included in a measurement specified by the SINC_LEVEL0.LCNT bits. The
valid value must be one less than a desired count (1 to 8), meaning the valid value is 0
to 7.
