Toggling OE# (LOW to HIGH to LOW) updates the status register.
To ensure the availability of correct status, please follow the
timings shown in Figure 20 on page 50. This can be done in
place of issuing the READ STATUS REGISTER command. Repeat
for subsequent programming operations.
After each program operation or after a sequence of
programming operations, an SR full status check can be done.
Write FFh after the last program operation to place the 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.
SR4, SR3, and SR1 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.
