Test R1-th bit in R0H (EBR1)
R0: EBR1/EBR2
R1: used to test R1-th bit in R0
Starting transfer destination address (RAM)
#RAMSTR + #ERVADR
ER2: address of data area used in RAM
Set EV bit
R5: set erase-verify loop counter
Program
Wait
R1L = #10?
If finished checking all R0 bits, branch to HANTEI
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 ≠ #FF, branch to ADD02
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
