This field contains bits [7:0] of the base alignment. The base
alignment provides the increment for the minimum base
address.
This field contains bits [15:8] of the base alignment. The base
alignment provides the increment for the minimum base
address.
This field contains bits [23:16] of the base alignment. The
base alignment provides the increment for the minimum base

This field contains bits [31:24] of the base alignment. The
base alignment provides the increment for the minimum base
address.
This field contains bits [7:0] of the memory range length. The
range length provides the length of the memory range in 1-
byte blocks.
