DO n (or b) = Data Out from column n (or column b)
BA A Col n (b) = Bank A, Column n (b)
Burst Length = 4; 3 subsequent elements of Data Out appear in the programmed order following DO n (b)
DO n, etc. = Data Out from column n, etc.
n', x', etc. = Data Out elements, according to the programmed burst order
BA, Col n = Bank A, Column n
Burst Length = 2, 4, 8 or 16 in cases shown (if burst of 4, 8 or 16, the burst is interrupted)
