INDOW CONTROL REGISTERS
There are three control registers for each window. Window 1 occupies columns 0 to 2 of row 10, columns 3 to 5 of
row 10 are occupied by window 2 and columns 6 to 8 of row 10 are occupied by window 3. If window overlapping occurs,
the highest priority window will cover the lowest. Window 1 has the highest priority and window 3 the lowest.
