AADR

[13:0]

Address. This is the starting address of the data array or mask array during

a burst READ operation. It automatically increments by 1 for each

successive read of the data array or mask array. Once the operation is

complete, the contents of this field must be reinitialized for the next

operation.

Reserved.

BLEN

[27:19]

Length of Burst Access. The device provides the capability to read from 4

up to 511 locations in a single burst. The BLEN decrements automatically.

Once the operation is complete, the contents of this field must be reinitialized

for the next operation.
