REJ09B0261-0100
•
Cache snoop functions are supported when the PCIC is a target (cache coherency can be
supported by sacrificing performance).
•
Supports four external interrupt inputs (
INTA
,
INTB
,
INTC
, and
INTD
) in host mode
•
Supports one external interrupt output (
INTA
) in normal mode
•
Both big endian and little endian are supported in SH7785 (the PCI bus operates in little
endian mode).
Note: The following PCI functions are not supported.
•
Supports cache (without the
SBO
and SDONE pins)
•
Address wraparound mechanism
•
PCI JTAG (this LSI supports JTAG)
•
Dual address cycles
•
Interrupt acknowledge cycles
•
Start of fast back-to-back transfer (it is supported when the PCIC operates as a target device)
•
Extended ROM for initialization, and boot of system
