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.
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.
