Section 9 Bus State Controller (BSC)
(12) Power-On Sequence
In order to use SDRAM, mode setting must first be made for SDRAM after waiting for the
designated pause interval after powering on. This pause interval should be provided by a power-on
reset generating circuit or software.
To perform SDRAM initialization correctly, the bus state controller registers must first be set,
followed by a write to the SDRAM mode register. In SDRAM mode register setting, the address
signal value at that time is latched by a combination of the CSn, RASU, RASL, CASU, CASL,
and RD/WR signals. If the value to be set is X, the bus state controller provides for value X to be
written to the SDRAM mode register by performing a write to address H'FFFC4000 + X for area 2
SDRAM, and to address H'FFFC5000 + X for area 3 SDRAM. In this operation the data is
ignored, but the mode write is performed as a byte-size access. To set burst read/single write, CAS
latency 2 to 3, wrap type = sequential, and burst length 1 supported by the LSI, arbitrary data is
written in a byte-size access to the addresses shown in table 9.18. In this time 0 is output at the
external address pins of A12 or later.
