Dummy write
Set erase-verify loop counter
Wait loop
Read
Read data = H'FF?
If read data ≠ H'FF, branch to BLKAD
Start address of next block
Last address in block?
If R1L ≥ 8, EBR1 test; if R1L < 8, EBR2 test
R1L – 8
Clear bit R1H in EBR1 (R0H)
Clear bit R1L in EBR2 (R0L)
R1L + 1
Clear EV bit
If EBR1/EBR2 = all 0s, normal end of erase
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
