Section 13 PCI Controller (PCIC)
• Exclusive access (target only)
• Can support cache coherency between a device connected to the PCI bus and system memory
• Supports four external interrupt inputs (INTD to INTA) in host bus bridge mode
• Supports one external interrupt output (INTA) in normal mode
• Supports both big endian and little endian formats for the SuperHyway bus (the PCI bus
• Number of devices which can be connected
The PCIC does not support the following PCI functions.
• Cache support (no SBO or SDONE pin)
• Address wrap-around mechanism
• PCI JTAG (other modules in this LSI can support the JTAG feature)
• Dual address cycles
• Interrupt acknowledge cycles
• Fast back-to-back transfer initiation (supported when performed as a target device)
• Extended ROM for initialization and system boot
Note: When the ratio of the clocks (SHwy clock : PCICLK clock) is in the ranges of (2.1 : 1) to
