Memory Bus Width: The memory bus width in the SH7729R can be set for each area. In area 0,
external pins can be used to select byte (8 bits), word (16 bits), or longword (32 bits) on power-on
reset. The correspondence between the external pins (MD4 and MD3) and the memory size is
shown in table below.
Table 11.4 Correspondence between External Pins (MD4 and MD3) and Memory Size
For areas 2–6, byte, word, and longword can be chosen for the bus width using bus control register
2 (BCR2) whenever ordinary memory, ROM, or burst ROM are used. When the synchronous
DRAM interface is used, word or longword can be chosen as the bus width.
When the PCMCIA interface is used, set the bus width to byte or word. When synchronous
DRAM is connected to both area 2 and area 3, set the same bus width for areas 2 and 3. When
using the port function, set each of the bus widths to byte or word for all areas. For more
information, see section 11.2.2, Bus Control Register 2 (BCR2).
