MMU
Stores the upper 19 bits of the 29-bit external address of the data line to be cached. The tag is
not initialized by a power-on or manual reset.
Indicates that valid data is stored in the cache line. When this bit is 1, the cache line data is
valid. The V bit is initialized to 0 by a power-on reset, but retains its value in a manual reset.
