Repeat for subsequent block erasures.
Full Status Check can be done after each block erase or after a sequence of
block erasures.
Write FFH after the last write operation to reset device to read array mode.
SR. 1 and 3 MUST be cleared, if set during an erase attempt, before further
attempts are allowed by the Write State Machine.
SR.1, 3, 4, 5 are only cleared by the Clear Staus Register Command, in cases
where multiple bytes are erased before full status is checked.
If an error is detected, clear the status register before attempting retry or other
error recovery.
