Note:

For configurations with CHI interfaces and optional DSSBs, Figure 2-10 CCN-502 clock domains with optional DSSBs shows the applicable device domain node IDs.

The power domains are used as follows:

LOGIC power domain
All logic except HN-F L3 tag and data RAMs and HN-F snoop filter RAMs.
L3RAM0 power domain
L3 tag/data RAMs way[7:0] for all 2 (6XP/2HNF) or 4 (8XP/4HNF) HN-F partitions. This is a single logical power domain across all partitions.
L3RAM1 power domain
L3 tag/data RAMs way[15:8] for all 2 (6XP/2HNF) or 4 (8XP/4HNF) HN-F partitions. This is a single logical power domain across all partitions.
SF power domain
Snoop filter RAMs for all 2 (6XP/2HNF) or 4 (8XP/4HNF) HN-F partitions. This is a single logical power domain across all partitions.
Optional DMC DSSB power domains
CCN502_SNF_DSSB logical power domain. There is a unique domain for each DSSB instance.
Optional processor DSSB power domains
CCN502_RNF DSSB logical power domain. There is a unique domain for each DSSB instance.
