1) DQ6 provides Lock Status of each block after writing the Read Lock Status command (71H).
F-WP# pins must not be switched during performing Erase / Write operations or WSM Busy (WSMS = 0).
2) Erase/Write command for locked blocks is aborted. At this time read mode is not array read mode but status read mode and
00B0H is read. Please issue Clear Status Register command plus Read Array command to change the mode from status read mode
to array read mode.

*The F-RY/BY# is an open drain output pin and indicates status of the internal WSM. When low,it indicates that the WSM is Busy performing an operation.
A pull-up resistor of 10K-100K Ohms is required to allow the F-RY/BY# signal to transition high indicating a Ready WSM condition.
*DQ3 indicates the block status after the page programming, byte/word programming and page buffer to flash. When DQ3 is "1", the page has the
over-programed cell . If over-program occurs, the device is block fail. However if DQ3 is "1", please try the block erase to the block. The block may revive.
