Address Multiplexing: An address multiplexing is specified so that SDRAM can be connected
without external multiplexing circuitry according to the setting of bits BSZ[1:0]in CSnBCR,
AxROW[1:0] and AxCOL[1:0] in SDCR. Tables 12.12 to 12.17 show the relationship between the
settings of bits BSZ[1:0], AxROW[1:0], and AxCOL[1:0] and the bits output at the address pins.
Do not specify those bits in the manner other than this table, otherwise the operation of this LSI is
not guaranteed. A25 to A18 are not multiplexed and the original values of address are always
output at these pins.
When the data bus width is 16 bits (BSZ[1:0] =B’10), A0 of SDRAM specifies a word address.
Therefore, connect this A0 pin of SDRAM to the A1 pin of the LSI; the A1 pin of SDRAM to the
A2 pin of the LSI, and so on. When the data bus width is 32 bits (BSZ[1:0] =B’11), the A0 pin of
SDRAM specifies a longword address. Therefore, connect this A0 pin of SDRAM to the A2 pin of
the LSI; the A1 pin of SDRAM to the A3 pin of the LSI, and so on.
