DRAM Address and Control Registers (DACR0/DACR1)
The DACRn registers, shown in Figure 15-3, contain the base address compare value and the control bits
for memory blocks 0 and 1 of the SDRAM controller. Address and timing are also controlled by bits in
DACRn.
Table 15-5 describes DACRn fields.

BA
Base address register. With DCMR[BAM], determines the address range in which the associated
DRAM block is located. Each BA bit is compared with the corresponding address of the current bus
cycle. If all unmasked bits match, the address hits in the associated DRAM block. BA functions the
same as in asynchronous operation.
