Synchronous DRAM Controller Module
7.6.4
In this example, only the second 512 Kbyte block of each 1 Mbyte space is accessed in each bank. In
addition the SDRAM component is mapped only to readable and writable supervisor and user data. The
DMRs have the following configuration.
With this configuration, the DMR0 = 0x0074_0075, as described in

DMR Initialization
With bits 17 and 16 as don’t cares, BAM = 0x0074, which leaves bank select bits and upper 512K select bits
unmasked.
Bits 22 and 21 are set because they are used as bank selects; bit 20 is set because it controls the 1-MB
boundary address.
