FF_SKIP_CNT
The proximity detection fast FIFO is used by the on-chip logic
to determine if proximity is detected. The fast FIFO expects to
receive samples from the converter at a set rate. FF_SKIP_CNT
is used to normalize the frequency of the samples going into the
FIFO, regardless of how many conversion stages are in a sequence.
In Register 0x002, Bits[3:0] are the fast filter skip control,
FF_SKIP_CNT. This value determines which CDC samples
are not used (skipped) by the proximity detection fast FIFO.
Determining the FF_SKIP_CNT value is required only once
during the initial setup of the capacitance sensor interface.
Table 13 shows how FF_SKIP_CNT controls the update rate of
the fast FIFO. The recommended value for the setting when
using all 12 conversion stages on the AD7147 is 0000, or no
samples skipped.
