1. Toggling OE (low to high to low) updates the status
register. This can be done in place of issuing the Read
Status Register command. Repeat for subsequent pro-
gramming operations.
SR full status check can be done after each program
operation, or after a sequence of programming opera-
tions.
Write FFH after the last program operation to place
device in read array mode.

Toggling OE (low to high to low) updates the status
register. This can be done in place of issuing the Read
Status Register command. Repeat for subsequent pro-
gramming operations.
SR.4, SR.3, and SR.1 are only cleared by the Clear
Status Register Command in cases where multiple lo-
cation are programmed before full status is checked.
If an error is detected, clear the status register before
attempting retry or other error recovery.
