Back-to-back diodes between ground domains and local clamps for signals crossing supply domains, protecting receivers during CDM events.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
