Table 1.26.1 lists the software commands available with the M16C/62A (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.

The status register is explained in the next section.
This command is used to clear the bits SR3 to 5 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 code
