description: |
  The AMS (Analog Monitoring System) includes an ADC as well as on-chip sensors
  that can be used to sample external voltages and monitor on-die operating
  conditions, such as temperature and supply voltage levels.
  The AMS has two SYSMON blocks which are PL (Programmable Logic) SYSMON and
  PS (Processing System) SYSMON.
  All designs should have AMS registers, but PS and PL are optional. The
  AMS controller can work with only PS, only PL and both PS and PL
  configurations. Please specify registers according to your design. Devicetree
  should always have AMS module property. Providing PS & PL module is optional.

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.
