(25) PCI Cache Snoop Control Register 1 (PCICSCR1)
An external 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 PCICSAR1. For details, see section 13.4.4 (7), Cache Coherency.

Description
Snoop Mode for PCICSAR0
These bits specify whether PCICSAR0 is compared
with the SuperHyway bus address requested by an
external device, or not. When PCICSAR0 is specified
to be compared, a condition to issue snoop
commands can be specified.
00: PCICSAR0 is not compared
01: Reserved (setting prohibited)
10: PCICSAR0 is compared. If the address matches
11: PCICSAR0 is compared. If the address matches
