FULL ERASE STATUS CHECK PROCEDURE
Repeat for subsequent block erasures.
Full Status register check can be done after each block erase
or after a sequence of block erasures.
Write 0xFF after the last operation to enter read array mode.
Only the Clear Status Register command clears SR[1, 3, 4, 5].
If an error is detected, clear the Status register before
attempting an erase retry or other error recovery.
