Transient Sensitivity (Bits 6–0)
Controlled by the application.
This register determines the number of consecutive out-of-window samples required to consider the
sequence a valid debounce count. The field works as a mask. Increasing the mask size (i.e. more bits
set to 1) will increase the noise immunity of the engine but result in lower sensitivity to subtle motion
signals.
Valid values are 01h, 03h, 07h, 0Fh, 1Fh, 3Fh, 7Fh, and FFh.
Controlled by the application.
This register determines how sensitive the transient detection part of the engine is to sudden changes
in the PIR signal. A lower number makes the engine more sensitive, at the cost of potential rejection of
large signal motion (ex. warm target very close to detector).
The valid range is 0 (disabled) to 64h.
