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 programming operations.
SR full status check can be done after each program operation, or
after a sequence of programming operations.
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 programming operations.
SR.4, SR.3 and SR.1 are only cleared by the Clear Status Register
command in cases where multiple locations are programmed before
full status is checked.
If an error is detected, clear the status register before attempting retry
or other error recovery.
