38C5 Group (One Time PROM version)
ROM Code Access Protection
We would like to support a simple ROM code protection function that
prevents a party other than the ROM-code owner to read and repro-
gram the builit-in PROM code of the MCU.
The MCU has 7 bytes of dedicated ROM spaces in address 0xFFD4
to 0xFFDA, as an ID-code (referred to as “the ID-code”) enabling a
Programmer to verify with the input ID-code and validate further op-
erations.
Expected Programmer ID-Code Verification
Function
First, Programmer must check the ID-code of the MCU.
If the ID-code is still in blank, Programmer enebles all operations,
Read, Program, and Program-Verify.
When Programmer programs the MCU, Programmer also programs
the given ID-code as well as the actual firmware.
If the ID-code is not blank, Programmer verifies it with the input ID-
code.
When the ID-codes don't mutch, Programmer will reject all further
operations.
If they match, Programmer perform operations according to the given
command.
