Protection Program operations can only be addressed within the protection
register address space. Addresses outside the defined space will return an
error.
Repeat for subsequent programming operations.
SR Full Status Check can be done after each program or after a sequence of
program operations.
Write FFH after the last program operation to reset device to read array mode.
SR.3 MUST be cleared, if set during a program attempt, before further
attempts are allowed by the Write State Machine.
SR.1, SR.3 and SR.4 are only cleared by the Clear Staus Register Command,
in cases of multiple protection register program operations before full status is
checked.
If an error is detected, clear the status register before attempting retry or other
error recovery.
