Figure 13.1 shows a block diagram of the PCIC.
The PCIC comprises two blocks, the PCI bus interface block and SuperHyway bus interface
block.
The PCI bus interface block comprises the PCI configuration register, local register, PCI master
controller, and PCI target controller.
The SuperHyway bus interface converts the access from the PCI bus interface into the access to
the SuperHyway bus, and converts the access from the SuperHyway bus (the CPU or DMAC) into
access to the PCI bus interface block. The SuperHyway bus interface block comprises PCIECR,
the access control block from the SuperHyway bus to the PCI bus, and the access control block
from the PCI bus to the SuperHyway bus.
The interrupt controller controls the issue of interrupts to INTC of this LSI.
