Internal Flash memory
4.5.6

Flash non volatile access protection register 0
Due to ST10 architecture, the XFLASH is seen as external memory: this made impossible to
access protect it from real external memory or internal RAM.

Access Protection
This bit, if programmed at 0, disables any access (read/write) to data mapped inside
IFlash Module address space, unless the current instruction is fetched from one of the
two Flash modules.
Debug Protection
This bit, if erased at 1, allows to by-pass all the protections using the Debug features
through the Test Interface. If programmed at 0, on the contrary, all the debug features,
the Test Interface and all the Flash Test modes are disabled. Even STMicroelectronics
will not be able to access the device to run any eventual failure analysis.
Protections Disable 15-0
If bit PDSx is programmed at 0 and bit PENx is erased at 1, the action of bit ACCP is
disabled. Bit PDS0 can be programmed at 0 only if bits DBGP and ACCP have already
been programmed at 0. Bit PDSx can be programmed at 0 only if bit PENx-1 has
already been programmed at 0.
