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

SR.5, SR.4, SR.3 and SR.1 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.
