Section 13 PCI Controller (PCIC)
(3)
Configuration Registers: Access the configuration registers using an offset from the PCI
configuration register space base address with the configuration read or write command. Only a
single access which size should be under longword is performed. If a burst transfer is attempted, it
is terminated to end the transaction.
Local Registers: Access the local registers using an offset from a PCI local register space base
address with the I/O read or I/O write command. Only a single longword access is performed. If a
burst transfer is attempted, it is terminated to end the transaction.
Control Register (PCIECR): Do not read or write access to the PCIECR from the PCI local bus.
(4)
Memory Space: Refer to Section 13.4.4 (1), Accessing This LSI Address Space. Area 0 to area 2
and area 4 to area 6 and DDR-SDRAM space on this LSI address space can be accessed.
On-chip IO Space: Do not read or write access to the on-chip IO space using memory read or
memory write command via PCI local bus. The operation of this read/write is not guaranteed.
