11.5.4 DMR Initialization
In this example, again, 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 Table 11-36.

Chapter 11. Synchronous/Asynchronous DRAM Controller Module
With bits 17 and 16 as don’t cares, BAM = 0x0074, which leaves bank select bits and
upper 512K select bits unmasked. Note that bits 22 and 21 are set because they are used
as bank selects; bit 20 is set because it controls the 1-Mbyte boundary address.
