A2 of this LSI, and A1 of the synchronous DRAM is connected to A3 of this LSI, the value
actually written to the synchronous DRAM is the value of “X” shifted 2 bits to the right.
For example, to write H'0230 to the area 2 SDMR register, arbitrary data is written to address
H'FF900000 (address “Y”) + H'08C0 (value “X”) (= H'FF9008C0). As a result, H'0230 is written
to the SDMR register. The range of value “X” is H'0000 to H'0FFC.
Similarly, to write H'0230 to the area 3 SDMR register, arbitrary data is written to address
H'FF940000 (address “Y”) + H'08C0 (value “X”) (= H'FF9408C0). As a result, H'0230 is written
to the SDMR register. The range of value “X” is H'0000 to H'0FFC.
The lower 16 bits of the address are set in the synchronous DRAM mode register.
The burst length is 4 and 8*. Setting to SDMR writes into the following addresses in byte size.
