ID codes are stored in addresses 0FFFDF16, 0FFFE316, 0FFFEB16, 0FFFEF16, 0FFFF316, 0FFFF716,
and 0FFFFB16. If wrong data are written to theses addresses, the flash memory cannot be read or written
in standard serial I/O mode.
The ROMCP register is mapped in address 0FFFFF16. If wrong data is written to this address, the flash
memory cannot be read or written in parallel I/O mode.
In the flash memory version of microcomputer, these addresses are allocated to the vector addresses (H)
of fixed vectors.
