title: ZynqMP Mode Pin GPIO controller
description:
PS_MODE is 4-bits boot mode pins sampled on POR deassertion. Mode Pin
GPIO controller with configurable from numbers of pins (from 0 to 3 per
PS_MODE). Every pin can be configured as input/output.

Annotation
- 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.
