Locking columns and rows
The content of any column or row can be locked during scroll. The content of locked
rows/columns does not move during scroll. Locked rows/columns always display the
content of pattern 1.
Any combination of columns can be locked by corresponding bits in the column lock
registers. Besides, any combination of rows can be locked by corresponding bits in the row
lock register. Columns and rows can be locked at the same time.
