PCI Cache Snoop Control Register 0 (PCICSCR0)
An external PCI device can access memory of this LSI via the PCIC. When an PCI device
accesses a cacheable area, the PCIC can issue cache snoop commands to the on-chip caches. This
register can specify the function that uses PCICSAR0. For details, see section 13.4.4 (7), Cache
Coherency.
