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
reprogram the built-in PROM code of the MCU.
First, Programmers must check the ID-code of the MCU.
If the ID-code is not blank, Programmer verifies it with the input ID-
code. When the ID-codes do not match, Programmer will reject all
further operations.
The MCU has each 10 bits of dedicated ROM spaces in address
009016 to 009616, as an ID-code (referred to as “the ID-code”) en-
abling a Programmer to verify with the input ID-code and validate
further operations.
