Two-Plane Block Erase
Basic concept of Two-Plane Block Erase operation is identical to that of Two-Plane Page Program. Up to two blocks, one from each
plane can be simultaneously erased. Standard Block Erase command sequences (Block Erase Setup command(60h) followed by
three address cycles) may be repeated up to twice for erasing up to two blocks. Only one block should be selected from each plane.
The Erase Confirm command(D0h) initiates the actual erasing process. The completion is detected by monitoring R/B pin or Ready/
Busy status bit (I/O 6).
