13. PCI Controller (PCIC)
• 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
