Test R1-th bit in R0L (EBR2)
If R1-th bit in R0 is 1, branch to ERSEVF
R1L + 1
Dummy-increment R2
ER3: top address of block to be erase-verified
ER4: top address of next block
Dummy write
R5: erase-verify loop counter
Wait
Read
Read data = #FF?
If read data
Last address in block?
If not last address in block, branch to EVR2
Clear R1L-th bit in R0H (EBR1)
Clear R1L-th bit in R0L (EBR2)
R1L + 1
Erase-verify next erased block
Clear EV bit
Clear bit of erased block to 0
If EBR1/EBR2 is all 0, erasing ended normally
E6 = 025A? (erase-verify fail count = 602?)
If E6 = 025A, branch to ABEND2
Erase-verify fail count + 1
Erase executed 4-times?
Double erase loop counter value
Erase again
