Description
Data Bus Width Specification
Specify the data bus widths of spaces.
00: Reserved (setting prohibited)
01: 8-bit size
10: 16-bit size
11: 32-bit size
For MPX-I/O, selects bus width by address
Notes:
Reserved
These bits are always read as 0. The write value
should always be 0.
1. If area 5 is specified as MPX-I/O, the bus
2. The initial data bus width for areas 0 to 7
3. If area 6 is specified as burst MPX-I/O
4. If area 5 or area 6 is specified as PCMCIA
5. If area 2 or area 3 is specified as SDRAM
6. If area 0 is specified as clocked
7. Area 7 cannot be used when the bus width
width can be specified as 8 bits or 16 bits
by the address according to the SZSEL bit
in CS5WCR by specifying the BSZ[1:0]
bits to 11. The fixed bus width can be
specified as 8 bits or 16 bits
is specified by external pins. The BSZ[1:0]
bits settings in CS0BCR are ignored but
the bus width settings in CS1BCR to
CS7BCR can be modified.
space, the bus width can be specified as
32 bits only.
space, the bus width can be specified as
either 8 bits or 16 bits.
space, the bus width can be specified as
either 16 bits or 32 bits.
synchronous burst ROM space, the bus
width can be specified as either 16 bits or

is specified as 8 bits. When using area 7,
the bus width should be specified as 16
bits or 32 bits for all areas in use.
