ATmega88P/PV and ATmega168P/PV 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
ATmega48P/PV, there is no Read-While-Write support and no separate Boot Loader Section. The SPM
instruction can execute from the entire Flash.
