Sequential Read
In read modes (1), (2), and (3), when a command (00H, 01H, 50H) is input and an address specified, if it is in the
block that includes the address that was specified first, the address is automatically incremented and the read
operation is continuously performed until the last address in the same block, by inputting the RE# clock. At this time,
a Busy period (tR) occurs after the last address is accessed in a page.

Note :To perform read again after reading the 527th byte of data of the last page of block, stop the read operation once, and
then restart the read operation by inputting again the read command and an address.

Note
Sequential read mode (1)
(When "00H" command is input)
Sequential read mode (2)
(When "01H" command is input)
Sequential read mode (3)
(When "50H" command is input)
Note : When the "50H" command is set, only the (C) area (redundancy data part) is continuously read.
• When the "00H" command is set, the start address (SA) is set to area (A).
• When the "01H" command is set, the start address (SA) is set to area (B).
• When the "50H" command is set, the start address (SA) is set to area (C).
