Section 9 Bus State Controller (BSC)
(3)
A burst read occurs in the following cases with this LSI.
• Access size in reading is larger than data bus width.
• 16-byte transfer in cache miss.
• 16-byte transfer by DMAC
• 16-byte to 128-byte transfer by LCDC
This LSI always accesses the SDRAM with burst length 1. For example, read access of burst
length 1 is performed consecutively 4 times to read 16-byte continuous data from the SDRAM that
is connected to a 32-bit data bus. This access is called the burst read with the burst number 4.
Table 9.17 shows the relationship between the access size and the number of bursts.
Note: For details, see section 24, LCD Controller (LCDC).
