Repeat for subsequent lock-bit operations.
Full status check can be done after each lock-bit set operation or after
a sequence of lock-bit set operations.
Write FFH after the last lock-bit set operation to place device in read
array mode.
SR.5, SR.4 and SR.3 are only cleared by the Clear Status Register
command, in cases where multiple lock-bits are set before full status is
checked.
If an error is detected, clear the status register before attempting retry
or other error recovery.
