ATmega48A/48PA/88A/88PA/168A/168PA/328/328P support a real Read-While-Write Self-Pro-
gramming 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.
