Repeat for subsequent blocks.
Full Status check can be done after each block or after a sequence
of blocks.
Write FFH after the last block erase operation to reset the device to
Read Array Mode.

1 = Block Erase Error
SR.3 MUST be cleared, if set during a erase attempt, before further
attempts are allowed by the Write State Machine.
SR.3 is only cleared by the Clear Status Register Command, in
cases where multiple blocks are erased before full status is
checked.
If error is detected, clear the Status Register before attempting retry
or other error recovery.
