ATmega48A/PA/88A/PA/168A/PA/328/P 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 ATmega 48A/48PA there is no Read-While-Write support and no separate Boot
Loader Section. The SPM instruction can execute from the entire Flash.
