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 FFh after the last operation to enter read array mode.
SR. 1 and 3 MUST be cleared before the Write State Machine
will allow further erase attempts.
Only the Clear Staus 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.
