Last address in block?
Clear EV bit
Erase-verify address – 1
Erase-verify fail count = 4?
If R6 ≥ 4. branch to BRER (branch until R6 = 4 – 602)
If R6 < 4, double erase time (executed only for R6 = 1, 2, 3)
Erase-verify executed 602 times?
If erase-verify not executed 602 times, erase again
If erase-verify executed 602 times, branch to ABEND2
