S3C4510B
CONTROL REGISTERS
SYSTEM CONFIGURATION REGISTER (SYSCFG)
The System Manager has one system configuration register, SYSCFG. The SYSCFG register determines the
start address of the System Manager's special registers and the start address of internal SRAM. (The total special
register space in the system memory map is fixed at 64 K bytes.)
You also use SYSCFG settings to control write buffer enable, cache enable, and stall enable operations.
All DRAM banks can be configured to SDRAM banks by set the Synchronous DRAM mode (SYSCFG[31]).
SYSCFG
If you write a "10" into the cache mode field, SYSCFG[5:4], the cache enable bit is cleared automatically
(see Figure 4-6).
