11.3.2.3 DRAM Controller Mask Registers (DMR0/DMR1)
The DRAM controller mask registers (DMR0 and DMR1), shown in Figure 11-4, include
mask bits for the base address and for address attributes.

Figure 11-4. DRAM Controller Mask Registers (DMR0 and DMR1)
Base address mask. Masks the associated DACRn[BA]. Lets the DRAM controller connect to various
DRAM sizes. Mask bits need not be contiguous (see Section 11.5, “SDRAM Example.”)
0 The associated address bit is used in decoding the DRAM hit to a memory block.
1 The associated address bit is not used in the DRAM hit decode.
Reserved, should be cleared.
Write protect. Determines whether the associated block of DRAM is write protected.
0 Allow write accesses
1 Ignore write accesses. The DRAM controller ignores write accesses to the memory block and an
Reserved, should be cleared.
Port size. Determines the port size of the associated DRAM block. For example, if two 16-bit wide
DRAM components form one DRAM block, the port size is 32 bits. Programming PS allows the
DRAM controller to execute dynamic bus sizing for associated accesses.
00 32-bit port
01 8-bit port
1x 16-bit port
Page mode. Configures page-mode operation for the memory block.
00 No page mode
01 Burst page mode (page mode for bursts only)
10 Reserved
11 Continuous page mode
Reserved, should be cleared.
Table 11-4. DACR0/DACR1 Field Description (Continued)
address exception occurs. Write accesses to a write-protected DRAM region are compared in the
chip select module for a hit. If no hit occurs, an external bus cycle is generated. If this external bus
cycle is not acknowledged, an access exception occurs.
