Transfer destination start address (RAM)
#RAMSTR + #ERVADR
Address of data area used in RAM
Used to test bit R1L in R0
Set erase-verify loop counter
Set EV bit
Wait loop
R1L = H'0C?
If finished checking all R0 bits, branch to HANTEI
If R1L ≥ 8, EBR1 test; if R1L < 8, EBR2 test
R1L – 8
Test bit R1H in EBR1 (R0H)
If bit R1H in EBR1 (R0H) is 1, branch to ERSEVF
If bit R1H in EBR1 (R0H) is 0, branch to ADD01
Test bit R1L in EBR2 (R0L)
If bit R1L in EBR2 (R0L) is 1, branch to ERSEVF
R1L + 1
Dummy-increment R2
Branch to ERASE via ERASE1
Start address of block to be erase-verified
