Again, 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

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.
