Section 9 Bus State Controller (BSC)
(13) External Address/SDRAM Address Signal Multiplex
(a)
Either of addresses used for accessing external device or SDRAM is output through external
address pins. The SDRAM address is shifted internally by changing the settings of DDBW and
DSZ in SDmADR and BSIZE in SDCmCNT. The bank address is output on A16 and A15 and the
address is output on A14 to A2.
Table 9.16 External Address/SDRAM Address Pins
(b)
Tables 9.17 to 9.19 are the SDRAM configurations that to support for 8-, 16-, or 32-bit bus width.
These tables are featured to ease the understanding of the relationships between the SDRAM to
support and address multiplex.
Addresses addr27 to addr0 are the logical addresses used by the CPU and DMAC in access to the
SDRAM. The table below shows how the settings of DSZ and DDBW determine which signals
are output on the SDRAM-access pins.
