CPU Rewrite Mode (Flash Memory Version)
Table 1.29.1. List of software commands (CPU rewrite mode)
Note 1: When a software command is input, the high-order byte of data (D
Note 2: SRD = Status Register Data (Set an address to even address in the user ROM area)
Note 3: WA = Write Address (even address), WD = Write Data (16-bit data)
Note 4: BA = Block Address (Enter the maximum address of each block that is an even address.)
Note 5: D
Note 6: X denotes a given address in the user ROM area (that is an even address).

Table 1.29.1 lists the software commands available with the M16C/62N (flash memory version).
After setting the CPU rewrite mode select bit to 1, write a software command to specify an erase or
program operation. Note that when entering a software command, the upper byte (D
The content of each software command is explained below.

address is read out at the data bus (D
The read array mode is retained intact until another command is written.
However, please begin to read data in the following procedures when a user uses read array com-
mand after program command.
(1) Set FF
(2) Input the top address which FF
(3) Input the top address till FFFF
(4) Input top address +2
(5) Input top address +2 till FFFF
(6) Input an arbitrary address

The status register is explained in the next section.
This command is used to clear the bits SR4 and SR5 of the status register after they have been set.
These bits indicate that operation has ended in an error. To use this command, write the command
