Indicates whether a page is cacheable.
0: Not cacheable
1: Cacheable
Specifies the cache write mode.
0: Copy-back mode
1: Write-through mode
Specifies whether a buffered write is performed.
0: Buffered write (Data access of subsequent processing proceeds without waiting for the write
1: Unbuffered write (Data access of subsequent processing is stalled until the write has
to complete.)
