SDRAM Example
The DACRs should be programmed as shown in Figure 11-27.
This configuration results in a value of DACR0 = 0xFF88_0304, as described in
Table 11-35. DACR1 initialization is not needed because there is only one block.
Subsequently, DACR1[RE,IMRS,IP] should be cleared; everything else is a don’t care.
