The devices contain four peripheral register spaces. The spaces are categorized as follows:

Peripheral Frame 0: These are peripherals that are mapped directly to the CPU memory bus. See  Table 8-9.
Peripheral Frame 1: These are peripherals that are mapped to the 32-bit peripheral bus. See  Table 8-10.
Peripheral Frame 2: These are peripherals that are mapped to the 16-bit peripheral bus. See  Table 8-11.
Peripheral Frame 3: These are peripherals that are mapped to CLA in addition to their respective Peripheral Frame. See Table 8-12.

Registers in Frame 0 support 16-bit and 32-bit accesses.
If registers are EALLOW protected, then writes cannot be performed until the EALLOW instruction is executed. The EDIS instruction disables writes to prevent stray code or pointers from corrupting register contents.
The Flash Registers are also protected by the Dual Code Security Module.
