Section 7 Bus State Controller (BSC)
Burst Write: A burst write occurs in the following cases in this LSI.
1. Access size in writing is larger than data bus width.
2. Write-back of the cache
3. 16-byte transfer by E-DMAC (access to non-cacheable area)
This LSI always accesses SDRAM with burst length 1. For example, write access of burst length 1
is performed consecutively eight times to write 16-byte consecutive data to the SDRAM that is
connected to a 16-bit data bus. The relationship between the access size and the number of bursts
is shown in table 7.13.
Figure 7.15 shows a timing chart for burst writes. In burst write, the ACTV command is output in
the Tr cycle, the WRIT command is issued in the Tc1, Tc2, and Tc3 cycles, and the WRITA
command is issued to execute an auto-precharge in the Tc4 cycle. In the write cycle, the write data
is output simultaneously with the write command. After the write command with the
auto-precharge is output, the Trw1 cycle that waits for the auto-precharge initiation is followed by
the Tap cycle that waits for completion of the auto-precharge induced by the WRITA command in
the SDRAM. In the Tap cycle, a new command will not be issued to the same bank. However,
other CS areas and other banks can be accessed. The number of Trw1 cycles is specified by bits
TRWL1 and TRWL0 in CS3WCR. The number of Tap cycles is specified by bits WTRP1 and
WTRP0 in CS3WCR.
