ATmega88A and ATmega168A support a real Read-While-Write Self-Programming mechanism. There is
a separate Boot Loader Section, and the SPM instruction can only execute from there. In ATmega48A,
there is no Read-While-Write support and no separate Boot Loader Section. The SPM instruction can
execute from the entire Flash.
