Section 11 Local Bus State Controller (LBSC)
11.3
11.3.1
The architecture of this LSI provides a 32-bit address space. The virtual address space is divided
into five areas (P0 to P4 areas) according to the upper address value.
This LSI supports both a 29-bit and a 32-bit physical address space, and the LBSC supports a 29-
bit physical address space. The 29-bit physical address space is divided into eight areas (areas 0 to
7) according to the upper three bits [28:26] of an address and the LBSC can control areas 0 to 2
and 4 to 6 as an external memory space. The maximum capacity of each area used as an external
memory space is 64 Mbytes; the LBSC can control a total of 6 areas with a maximum capacity of
384 Mbytes as the external memory spaces.
A virtual address can be allocated to any physical address through the address translation function
of the MMU. For details, see section 7, Memory Management Unit (MMU).
With the LBSC, various types of memory or PC cards can be connected to each of the six areas as
shown in table 11.2, and accordingly output the chip select signals (CS0 to CS2, CS4 to CS6,
CE2A and CE2B). CS0 to CS2 are asserted when accessing areas 0 to 2 individually, and CS4 to
CS6 are asserted when accessing areas 4 to 6 individually. When the PCMCIA interface is
selected for area 5 or 6, CE2A or CE2B is asserted along with CS5 and CS6 for the bytes to be
accessed.
Area 3 is for DDR-SDRAM memory space and controlled by the DDR-SDRAM Interface
(DDRIF). For details, see section 12, DDR-SDRAM Interface (DDRIF).
Areas 2, 4, and 5 can also be used for the DDR-SDRAM memory space, and area 4 can also be
used for the PCI memory space by setting the Memory Address Map Select Register (MMSELR).
Area 7 is a reserved area. For the PCI memory space, see section 13, PCI Controller (PCIC). Both
DDRIF and PCIC support a 32-bit physical address space in addition to a 29-bit address. For a 32-
bit physical address, refer also to section 7.7, 32-Bit Address Extended mode.
