I see the LS1046A Processors Block Diagram contained CCI400
Solved! Go to Solution.
USB snooping is controlled by the SCFG_SNPCNFGC - refer to the LS1046A Reference Manual, 11.3.27 Snoop Configuration Register (SCFG_SNPCNFGCR).
PCIe snooping is controlled by "No Snoop" TLP attribute.
Frame Manager snooping is always enabled.
