Table 3-100 lists the encoding of the remapping for the primary memory type.
Figure 3-58 shows the arrangement of the bits in the Normal Memory Remap Register.

Table 3-101 lists how the bit values correspond with the Normal Memory Remap Register
functions.
b. Shareable attributes can map for both shared and non-shared memory. If the Shared bit
read from the TLB or page tables is 0, then the bit remaps to the Not Shared attributes
in this register. If the Shared bit read from the TLB or page tables is 1, then the bit
remaps to the Shared attributes of this register.
