Wait
Read data = H'00?
If read data = H'00, branch to PWVFOK
Prewrite-verify executed 6 times?
If prewrite-verify executed 6 times, branch
to ABEND1
Double prewrite loop counter value
Prewrite-verify fail count + 1
Prewrite again
Last address?
Address + 1
If not last address, prewrite next address
R0: erase-verify fail count
ER3: top address of block to be erased
Set initial erase loop counter value
R0 = H'025A? (erase-verify fail count = 603?)
If R0 = H'025A, branch to ABEND2
Erase-verify fail count + 1
