(1)Registers in Frame 0 support 16-bit and 32-bit accesses.

(2)If registers are EALLOW protected, then writes cannot be performed until the user executes the EALLOW instruction. The EDIS instruction disables writes. This prevents stray code or pointers from corrupting register contents.

(3)The Flash Registers are also protected by the Code Security Module (CSM).
