The Power-AP supports five debug directives for subdomain power status:
- POWER: Indicates the current power state of the functional logic in the managed subdomain
- DEBUGPOWER: Indicates the current power state of the debug logic in the managed subdomain
- POWERLOSS: Indicates that the domain has entered a powered off state at least once since the last time the bit was cleared
- RETENTION: Indicates that the domain has entered a non-functional retention state at least once since the last time the bit was cleared
- POWERDOWNDESIRED: Indicates that debug power controls are artificially preventing the domain from entering a powered down state
