mode (3) outputs the contents of the redundant address locations only. When the pointer reaches the last address,
the device continues to output the data from this address ** on each RE clock signal.

Once a 50H command has been issued, the pointer moves to
the redundant cell locations and only those 16 cells can be
addressed, regardless of the value of the A4-to-A7 address. (An
00H command is necessary to move the pointer back to the
0-to-511 main memory cell location.)
