Security Levels of the M32R Family
Security Level
Depending on the verification result and the security level, the following
accesses to the device is possible:
•
Security ID code matches:
Any access is possibly, there are no limitations
•
Security ID code does not match:
Security Level 0:
There is no access at all, even flashing is not possible. The debugger
generates an error message and remains in down state.
Security Level 1:
The debugger reaches up state, but all read/write access to the Flash memory,
to RAM, to registers and peripherals are blocked. No command will be accepted, except a
special command to erase the complete Flash area. Any attempt to execute a command (except
the Flash erase command) will cause an error message.
The special Flash erase command takes care that just a complete erased Flash allows access to
the device by the default Security ID code.
