ID Code
When the flash memory is not blank, the ID code sent from the peripheral units and the ID code written
in the flash memory are compared to see if they match. If the codes do not match, the command sent
from the peripheral units is not accepted. An ID code contains 8 bits of data. Area is, from the 1st byte,
addresses 0FFFDF16, 0FFFE316, 0FFFEB16, 0FFFEF16, 0FFFF316, 0FFFF716 and 0FFFFB16. Write
a program into the flash memory, which already has the ID code set for these addresses.
