Table 18.6 System Clock Frequencies for which Automatic Adjustment of LSI Bit Rate is
In boot mode, this LSI checks the contents of the 8-byte ID code area as shown below to confirm
that the programming control program corresponds with this LSI. To originally write a
programming control program to be used in boot mode, the above 8-byte ID code must be added at
the beginning of the program.

Note that the contents of the boot program area in RAM are remained after a branch is
made to the programming control program.
