of the ERASE SUSPEND operation, DQ7 outputs 1. For an ERASE operation in progress, DQ7 outputs 0;
upon ERASE operation’s successful completion, DQ7 outputs 1.
3. After successful completion of a PROGRAM, ERASE, or BLANK CHECK operation, the device returns to
read mode.
4. During erase suspend mode, READ operations to addresses within blocks not being erased output
memory array data as if in read mode. A protected block is treated the same as a block not being erased.
See the Toggle Flowchart for more information.
5. During erase suspend mode, DQ6 toggles when addressing a cell within a block being erased. The
toggling stops when the program/erase controller has suspended the ERASE operation. See the Toggle
Flowchart for more information.
6. When DQ5 is set to 1, a READ/RESET (F0h) command must be issued before any subsequent
command.
