PIR sensor for human detection.
Datasheet: https://www.endrich.com/Datenbl%C3%A4tter/Sensoren/D3-323-AA_e.pdf
properties:
compatible:
const: nicera,d3323aa
vdd-supply:
description:
Supply voltage (1.8 to 5.5 V).
vout-clk-gpios:
maxItems: 1
description:
GPIO for clock and detection.
After reset, the device signals with two falling edges on this pin that it
is ready for configuration (within 1.2 s).
During configuration, it is used as clock for data reading and writing (on
data-gpios).
After all this, when device is in operational mode, it signals on this pin
for any detections.
data-gpios:
maxItems: 1
description:
GPIO for data reading and writing. This is denoted "DO (SI)" in datasheet.
During configuration, this pin is used for writing and reading
configuration data (together with vout-clk-gpios as clock).
After this, during operational mode, the device will output serial data on
this GPIO.

Annotation
- Immediate include surface: `dt-bindings/gpio/gpio.h`.
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
