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.
