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.

Read Mode (3)
Sequential Read modes (1) and (2) output the contents of addresses 0~m as shown above, while Sequential Read

This mode allows the sequential reading of pages without additional address input.
Read mode (3) has the same timing as Read modes (1) and (2) but is used to access information in the extra

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.)
