Section 8 Bus State Controller (BSC)
Power-On Sequence
In order to use synchronous DRAM, mode setting must first be performed after powering on. To
perform synchronous DRAM initialization correctly, the bus state controller registers must first be
set, followed by a write to the synchronous DRAM mode register. In synchronous DRAM mode
register setting, the address signal value at that time is latched by a combination of the RAS, CAS,
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 synchronous DRAM mode register by performing a write to address H'FFFFD000 +
X for area 2 synchronous DRAM, and to address H'FFFFE000 + X for area 3 synchronous
DRAM. 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 1 to 3, wrap type = sequential, and burst length
1 supported by this LSI, arbitrary data is written in a byte-size access to the following addresses.
Mode register setting timing is shown in figure 8.27.
As a result of the write to address H'FFFFD000 + X or H'FFFFE000 + X, a precharge all banks
(PALL) command is first issued in the TRp1 cycle, then a mode register write command is issued
in the TMw1 cycle.
Address signals, when the mode-register write command is issued, are as follows:
