22.1.4
The PCIC has the PCI configuration registers and PCI control registers shown in table 22.2, 22.3
and 22.4. Also, the PCI bus address space is allocated to the internal bus for the peripheral
modules, making it possible to access the PCI bus by program IO (PIO). Not only do these
registers control the PCI bus but also enable high-speed data transfers between the PCI device and
memory on the SH-4 external data bus (hereinafter, the SH-4 external data bus is referred to as the
local bus to distinguish it from the PCI bus).
