When the security fuse in the Flash is programmed, the following aWire commands are limited:
Unlimited access to these instructions is restored when the security fuse is erased by the
CHIP_ERASE aWire command.
Note that the security bit will read as programmed and block these instructions also if the Flash
Controller is statically reset.
