2.3.2 RAM and I/O Mapping Register
The random-access memory (RAM) and input/output (I/O) mapping register (INIT) is a special-purpose
8-bit register that is used during initialization to change the default locations of RAM and control registers
within the MCU memory map. It can be written to only once within the first 64 E-clock cycles after a reset
in normal modes. Thereafter, it becomes a read-only register.
