ID check function
The command checks the ID code. Execute the command as follows:
(1) Transfer the command code “F516” in the 1^st byte.
(2) Transfer addresses A7–A0, A15–A8 and A23–A16 of 1^st ID code (ID1) in the 2^nd, 3^rd and 4^th bytes
respectively.
(3) Transfer the number of the ID code in the 5^th byte.
(4) From the 6^th byte onward, transfer the IDs from the 1^st ID code (ID1).

ID code
If the flash memory is not blank, the input ID codes are compared with that written in flash memory. If they do
not match, the input commands will not be accepted. Each ID code contains 8 bits data. Beginning from the
1^st ID byte, the address of each ID code is 0FFFDF16, 0FFFE316, 0FFFEB16, 0FFFEF16, 0FFFF316, 0FFFF716
and 0FFFFB16 respectively. Write the program with the ID codes in these addresses to the flash memory.
