Read Mode (3)
16-byte redundancy area of the page. The start pointer is therefore set to a value between byte 512 and byte

Read mode (3) has the same timing as Read modes (1) and (2), but it is used to access information in the extra

Addresses bits A0 to A3 are used to set the start pointer for the
redundant memory cells, while A4 to A7 are ignored.
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 or an 01h command is necessary to move the pointer back to
the 0 to 511 main memory cell location.)
