Bits Field Function a<br />

a. The reset values ensure that no remapping occurs at reset.<br />

b. Shareable attributes can map for both shared and nonshared memory. If the<br />

shared bit read from the TLB or translation tables is 0, then the bit remaps to<br />

the nonshared attributes in this register. If the shared bit read from the TLB or<br />

translation tables is 1, then the bit remaps to the shared attributes of this<br />

register.<br />
